I just installed a fresh 10.10 in a VM environment to check Thierry comment.
The problem by default does not occur because dovecot-postfix is now broken : if the config files are well installed for postfix, for dovecot there are created in sub directories (auth.d and conf.d) which are just plain ignored by the new default dovecot.conf. Therefore, no managesieve process nor dovecot-auth can be launched.
A patch could be to include the following lines :
!include /etc/dovecot/conf.d/*.conf
!include /etc/dovecot/auth.d/*.conf
at the end of dovecot.conf when installing dovecot-postfix.
And, not forget to include parsing of conf.d directory in the upstart /etc/init/doveconf package to look for imap4/pop3 protocols.
