with local imap: sent mail (Gcc) sometimes not saved

Hi,  I’m using Gnus (from Emacs 24.4.1) with a local dovecot and 
mbsync for synchronizing to remote IMAP servers [1].   This works 
really rather well.  There is, however, one problem:  I set the 
gcc-self Gnus parameter to save all outgoing mail.  Usually this 
works flawlessly, but from time to time I cannot find some message 
that I know that was sent out successfully (I can see it in my 
msmtp log, and I also already got replies to such messages).  Do 
you have any suggestions how to debug this?  I noticed that 
dovecot, when used directly through the /usr/lib/dovecot/imap 
executable, does not seem to log anything.  I tried to add the 
command line parameter 
 
 -o log_path=/home/myuser/.dovecot.log 
 
but nothing gets logged there.

For now, I've added "2>>$HOME/.dovecot.err" to the end of
nnimap-shell-program.  Nothing has appeared there so far, so I'm not too
confident to be able to catch the problem in this way.  Also, I'm not
even sure whether it's a dovecot problem at all.  It could be also due
to Gnus itself.

It's disquieting to randomly and quietly loose mail.  I'd love to fix this.

Christoph
