Comment 4 for bug 260899

The problem is the upstream courier packaging is very inconsistent; it even violates Debian's policy w.r.t. to shared libraries. the courier-authlib package has the following rdepends, so nothing outside of courier is directly dependent on it.

mcasadevall@blacksteel:~/packaging/xfce4.6-beta/xfwm$ apt-cache rdepends courier-authlib
courier-authlib
Reverse Depends:
  courier-mta
  maildrop
  courieruserinfo
  courierpasswd
  courierpassd
  courier-base
  courier-authlib-userdb
  courier-authlib-postgresql
  courier-authlib-pipe
  courier-authlib-mysql
  courier-authlib-ldap
  courier-authlib-dev
  courier-authdaemon
