Bug Description

Binary package hint: thunderbird

Microsoft Outlook allows to modify "subject" of incoming emails. This is very very useful, especially when sender used a meaningless subject, or a simple dot. This feature should be very useful also in Thunderbird.
Thanks a lot

Hi Morten,

I voted for this feature request becuase I would find it very useful and I think
many other mozilla users would find it useful.

By implementing it many people will be made happy, they will get use out of it,
and it will be one more factor in making mozilla popular.

We don't talk about a feature, that no one should have, at least half of all

If I want to fake an email, I just need to open the mail-folder-file. Any more

Current options are moving to folder, labeling the message, etc. but it would be
nice to be able to modify the subject line of matching messages to visually

Often I am copying my mail archives from one PC (e.g. my Windows laptop) to
another PC (my Linux workstation), after "compressing" the mail files. I
consider the .msf files not as part of the archive content but just as temporary
index files.

In addition, the msf files are automatically rebuilt each time my mozilla

Good points, but IMO:
- mails should not be altered
- comments are not part of the mail and do not belong into the mbox

So we'd need to put the comments into the msf (with the above problems) or we'd
need another file for the comments (which isn't desirable for performance reasons).

Since the msf problems are actually "just" bugs, I'm still in favor of that
solution - it would delay this bug until after resolving them, though.

Yes, the additionnal comments belong to the MSF file, just as the message flag

well, I'm thankful there are people that sometimes decide to label a bug
WONTFIX. Not doing so will inexorably lead to total mess in Mozilla developpment.

But Mozilla Mail is not the only mailer, you can post your request on the
Thunderbird forums on [http://www.mozillazine.org/forums/] , they may have a
different opinion.

If we want to store internal data in X-headers, we have to make sure that

That way, we could store comments etc. in some X-Mozilla-Comments header that is
only visible to Mozilla itself and would, eg., not be saved when saving messages
to files. (The mbox format already 'escapes' certain lines to work around problems.)

Alas, Mozilla's mbox handling is not 'transparent' in that respect (yet?), see
the empty line problem in bug 141983, bug 67391 and others.

C'm on Guys!

Is this really a chat thread for developers or just time capitalists that don't
know what else to do with their time? How hard can it be to realize the benefits
to the users this feature would bring?

The only blocker for this enhancement that I can see here is prestige. There has
not been presented one single rational argument to not implement this during one
year of ongoing discussion. There is no technical one - at least none I'm aware
of. Please prove me being wrong here.

Once a user has recieved a message, it's up to the user to decide what (s)he
wants to do with the message. Delete it, edit it or whatever. (S)he must take
take the consequenses of it anyway. If the sender wants to safeguard that the
"intellectual" contents of the message is not altered without being able to
prove that, then (s)he should choose to sign the message (or encrypt it), either
using S/MIME, PGP/MIME, or plain PGP.

None of the techniques above will become broken by changing the Subject Text of
the message. I've just verified that for all the six possibilities. Works like a
charm in Mozilla 1.5.

Another, at least as I see it, rational reason to allow changing the subject,
that has not been mentioned on this tread before, is the one that I reported
yesterday as Bug 229222 (and redirected to this thread).

For your convinience I include it here too:

Some of my mail forwarding services have started to "play" with spam
notification filters which, e.g. prepend "*** SPAM ***" to the subject line.
Unfortunately this once in a while gets added to the subject line of mails that
I receive from mailing lists. This, of course, breaks the sorting of mails by
"thread", and I thus have to manually open the Mail Folder with my Editor,
search for that particular mail and edit the subject back to it's original. I
don't see any reason to not allow this to be done via the Subject line of the
Header Pane in the Mail Viewer. And to my knowledge this shouldn't affect
signed/encrypted mail either.

This would also be useful when for changing an "internationalized" Reply Prefix
e.g. the Swedish "SV:" to the more common "Re:" which gets posted now an then to
 mailing lists where mainly english is spoken/written.

./.

This was annoying in Netscape, in Mozilla even more. Why?
Well, in Netscape one could switch to another folder during the edit, but in
Mozilla that isn't enough. One has to exit Mozilla and reenter, otherwise
something gets messed up and every mail is shown twice in the Mail Pane of the
Main Mail Window after the edit. Not to mention that, one will loose all labels
assigned to mails before the manual edit.

Concerning where to store the edited Subject Text; the answer is simple - in the
header of the mail. How should I otherwise, i.e. if that text has been stored in
the .msf file, be able to see that change when accessing my mail via my web-mail
client instead of via Mozilla (IMAP)? If you, for some reason, want to store the
original Subject Text somewhere, that's all right with me. Even in that .msf
file. I certainly do not care. But I'd suggest to add a new property header like
"X-[Mozilla-]Original-Subject: ..." to the message header (if there doesn't

(And Mozilla suite guys do not seem to want to implement it for some strange

In addition to being able to edit the subject line for the incoming mail
summary (not in the msg header), some users need to be able to insert a short
note into the body of the msg for future reference. For example, I receive
many technical newsletters and E-mails, and often insert short notes (like a
footnote) referring to some URL or other E-mail for related information.
The lack of this feature in Mozilla Thunderbird is a major reason preventing
me from switching. Eudora has this toggle - the Pencil button toggle, which
makes it possible to save it to the original msg.
Thunderbird has an "Edit this message as new" feature, but it saves the
modified msg separately in a different format, but it's clunky & doubles the
storage space required..

2. Why not include a separate field into the header set this field to the same
value as subject by default and then allow changing it. Various programs (spam
filters) include their fields into the header so the purists do not have to be
woried. You could switch this feature on or off.

Maybe itt would be also useful to allow including one more field for longer

With all respect, the feature you suggest (as point 2.) might be useful to some
people, even though I don't know precicely for what. But, if implemented, I
think it should be optionally configurable; not done by default.

My primary, and *urgent*, need for this feature is to actually restore subjects
to their original value again after having become "trashed" (e.g. by prepending
"*** SPAM ***" to the real subject), e.g. by external MTA spam filters (that are
not under my control, like http://www.snert.com/Software/milter-spamc/, etc), so
that those messages *again* will be filtered into the message thread they are
supposed to. For this purpose there is no value added by storing the "original"
subject.

Performing this task, by editing the mail file for each and every mail with an
"trashed" subject, is becoming more and more frustrating for every day and thus;
I'd like this primary and, IMHO for most of us, very useful feature to be given
a high priority.

I would also prefer direct editing of the subject, but it looks as there is no
way to get that since it is opposed for some puristic reasons. With the option I
suggested I would simply forget there was ever any Subject field and display the
new field as if it were subject field.

My reasons for this feature:
(1) the one you said with SPAM tagging,
(2) assigning reasonable subjects to articles I sent from various websites (e.g.
changing "An article from financialnews.cz" to "Mortgages from financialnews.cz"
(3) changing recycled subject: "re: problem with PDA" -> "How to get to the airport"

Actually, now, I *can* see at least one feature for which saving the original
subject in a separate header field could be of use. But that feature should be
implemented as an extension, that may *optionally* be enabled/applied *after*
direct editing the subject (e.g. for one of the reasons mentioned in comment
#31). If, after enabling this feature for an message, any follow-up messages
received with that same original subject *automagically* would be substituted by
the new subject, then that would be really useful.

But, the above suggested feature *should not* be considered if it in any way
delays the implementation of direct editing the subject line; e.g. as described
in comment #31.

I do willingly admit that I haven't analysed and considered any side-effects
that this might have. It was just an idea that happened to cross my mind.

I also have been using TB Header Tools and now on extension 7.1 which has a basic problem in that when a msg is being viewed and I go to View/Change Header Details, then the msg in focus is changed. This can make it very difficult to write the appropriate subject since it's usually something included in the msg.

A good example of a daily change that is made is a msg from Cybernet where the subject always is "CyberNet Technology News." If such a msg is to saved the actual content subject needs to be entered. This is needed for a later quick search to find the subject. Of course, the subject frequently needs to be changed in received business msgs as well because writers frequently do not include a subject at all or the subject is not related to the content.

As far as the various fields and minimal instructions with the extension, I don't understand one iota so simply change the subject line and happy I can do that. It would certainly be appreciated if this extension were to be incorporated into TB as a feature that could be used by those who need it.

FWIW, I agree that the original subject should NOT be overwritten, as apparently happens with the MailTags suggestion listed above. The optimum implementation IMHO would be the ability to highlight the subject and just edit it right there (which even the nefarious Outlook has). Second most optimum is the right-click option method, and last (mildly inconvenient but worlds better than no option at all) is to drill down for the option through the Message menu.

It would be most ideal to have this functionality in TB itself...and even I'm okay with having to go into Config Editor to manually enable it.

I agree that the optimum implementation, which the original Eudora does (I'm still running Eudora on my Mac and will do so until Lion) is the ability to highlight the subject and change it. Eudora has an editable subject line field at the top of the email message, as well as a Subject: display within the email that retains the original subject.

Why is this so difficult?

Sorry, my comment #73 may be misleading. MailTags does not overwrite the subject in the mail header.

Instead it adds custom headers to allow you to set your own subject line. This subject line will be displayed in message list pane (instead of the original subject line) and regarded in searches. However, you can always revert to the original subject line.

TB Header Tools 0.71 was great help to edit empty or useless subjects in order to find an important email again. But unfortunately I have not checked this forum before I upgraded to TB 5! Hopefully there will be soon an new solution, otherwise I might downgrade again or use another client.

I just found the new extension (as of Sept. 2011) "editemailsubject" (must be typed as written, without blanks, in Thunderbird's extensions search). It allows to edit the subject displayed in the mailbox window while preserving the subject in the message header. Exactly what I was looking for.

howdy y'all,

this extension from paolo kaosmos does the job. it replaces the old headertools extension mentioned in comment 37 and is actively supported.

The addon can be downloaded from here (reported to work with TB24, and actively maintained):

Why this is important:

1. You personally may not, but many users have fax->email services. For them, this feature is absolutely necessary. For a long time, I didn't realize that there was an extension that allows it and works well, the lack of which causing me a lot of pain.

2. If people set bad subjects for important emails (e.g. by just hitting reply on an unrelated subject), I can either get angry at them (because I will not find it anymore in one week), or ask them to fix it in the future, or I can fix it myself in my mail store. The latter, however, I can only do with this feature.

3. Many other people have wrong clocks on their computers, and Thunderbird sorts folders by the message send time that the sender put in. I recently received a mail which was exactly one month off. Completely confused me in the folder view. I can't fix it, without this feature. (Arguably, Thunderbird should sort better.)

This is similar to "delete attachment" feature. That's also a feature that we didn't have for a long time, and some said we didn't want it, they said it's freaky and wrong. Finally, we added it - and it's indispensable, as it turned out.

+1, I'd like to register my support for Ben's support of this bug :)

65 votes and 15 duplicates with consistent inflow over a large time span are a good indication that "edit subject" feature has the potential of adding significant value for many affected users.

Somebody care to search https://getsatisfaction.com/mozilla_messaging/ for user requests about this?

If you are suggesting that a larger or in any way significant percentage of TB users use FAX-to-Email services, then imho that's a fiction from the same ideosyncratic historic world where plaintext messages are still so much the order of the day that we could just ignore the substantial dataloss of formatting/styles inflicted on users of HTML messages by your delivery-format "Auto-Detect" algorithm.

Having said that, I don't think small numbers of users for a given feature is per se an argument against that feature; if we removed all features each only used by small percentage of users, we would end up removing large parts of TB feature set. On the contrary, I'd claim that qualitative aspects like the degree of disturbance by lost ux-efficiency should also matter. Which might apply to this bug: It's hard to tell how many users would actually bother to edit subjects, but for those affected by such problems, it's a significant interruption to their workflows.

This bug is only about editing subject; editing any other header fields (like date) is not in the scope of this bug, and should not. It'll be more than hard enough to just land "edit subject" in a generally acceptable and functional manner (think IMAP), so expanding the scope of this bug would be the perfect recipe for never landing anything.

OT: I have some doubts on that, given that the "delete/detach attachment" feature still has bugs (like wrong icon for detached files) without much activity from users iirc.

My .02 clad coins worth:

I might use this feature, but honestly, all I do now is simply forward the email as an attachment to myself, with the new subject.

Since I don't do this very often, it isn't that big of a deal, but I understand the argument for someone who may have a different workflow from me.

That said, I would only support implementing this feature if the act of modifying the email was recorded.

Ie, it adds a new header to the email, something like:

X-SubjectModified: OLD: Blahblah; NEW: blahBlahBlahBlah

In other words, the evidence (old subject) is still there.

+1 for me. Still would benefit my use of Thunderbird for mail storage/archival. My partner at work often sends empty subjects. It's annoying as hell --- but what's even more annoying is having to keep telling him. I'd prefer to just add a modified subject to the email with a record in the email header as described by Charles. - Thx

Previous headers should be recorded as "X-Original-<headername>", e.g.:

  Subject: Appointment to discuss Bla project
If X-Original-Foo already exists, it is *not* overwritten.

I fully agree with ben.bucksch' comment: it is good practice to keep a trace of trace of what the original Subject line showed.
Sometimes I like to edit the email itself to add comments/annotations to make the content more (re-)usable for myself. In that case I explicitly indicate (eg. by 'keyword' like "_ANNOTATIONS") that this was an entry added after receiving the email.
This feature is not 'comfortably' provided by all my favorite mail-clients though ;-)

It has been over six years since the last real discussion took place and almost two decades since the issue was created. Are there any objections from the Thunderbird team or hasn't there just been any volunteer to implement the feature?

I have another use-case for this feature: Many scanners nowadays can send emails with the scan attached. By default, though, these mails have a very generic subject. Being able to change the subject from the mail client conveniently allows finding particular scans later on.

I have been doing this in the past using the [Header Tools Lite](https://addons.thunderbird.net/de/thunderbird/addon/header-tools-lite/) addon. This addon, however, is not compatible with newer versions of Thunderbird. After looking through [Thunderbird's WebExtension APIs](https://thunderbird-webextensions.readthedocs.io/en/68/), it seems like editing an email's headers is no longer possible at all. It would be great if we could get at least an API to modify (or create new) mails.

I second the motion to add an API to Thunderbird that would allow changing the email subject in the folder list - not in the email itself, just like the last addon.

100% exactly my problem as well. This makes scan to email very hard to use. Everything has the same subject. Get 5 at the same time, and it's impossible to manage. Scan to email is a widely advertized feature of printers, so it's not a mainstream feature, and not marginal.
