The official Debian packages are indeed build against libfam.


This is likely the reason. Gamin might provide source-level compatibility  
with libfam, but it's unlikely to provide binary ABI-level compatibility.


The package should have an explicit dependency on libfam, and not allow to  
be installed together with Gamin.

Thank you Sam, the problem is fixed, thanks to this hint. But a funny
thing is that Gamin was installed and not FAM.  When I did an "apt-get
install fam libfam-dev" which automatically removed Gamin, imap worked
again. Thus there seemed to be a problem with Gamin, while FAM works
fine (on my system).

So, for folk having trouble with reading the maildir after they managed
to login through imap, switching from Gamin to FAM or the other way
around is a good idea to try out!


How did you install Courier-IMAP? Did you build it from source, or install a  
precompiled package? It's possible that the precompiled package gets built  
against libfam which is likely not to be binary ABI-compatible with gamin,  
even though the .so symbols are the same. So, imapd binds with the .so, but  
the binary ABI incompatibility is breaking everything. This might be one  
explanation.

Thank you Sam, the problem is fixed, thanks to this hint. But a funny
thing is that Gamin was installed and not FAM.  When I did an "apt-get
install fam libfam-dev" which automatically removed Gamin, imap worked
again. Thus there seemed to be a problem with Gamin, while FAM works
fine (on my system).

So, for folk having trouble with reading the maildir after they managed
to login through imap, switching from Gamin to FAM or the other way
around is a good idea to try out!

A login USERNAME PASSWORD2

and then it does nothing; it hangs.  I can only quit it by killing the
task or say couriertcpd.  The permissions of ~/Maildir/* are identical
(with correct respective user and group IDs).  I tried to remove
~/Maildir and recreate them with maildirmake, but even then user
USERNAME is not able to do B select INBOX, while user test is (also
with newly created Maildir).  Any ideas are welcome.

I am running Debian 6.0.6 with courier-imap 4.8.0-3.


There have been occasional reports of some kind of a problem with libfam in  
Debian that's causing this, with the actual cause being unknown.


Rebuilding courier-imap against Gamin, instead of FAM, usually fixes this.
