I don't, but I have seen reports of bad IMAP performance for Mail.app  
but no such report for dovecot, so it was my first assumption.

It could be a possibility. The strange thing is that it does not  
matter how many clients are connected, the behavior is often the  
same: messages are copied or deleted one per minute (it seems), and I  
see every minute in the log things like:
Jun 28 16:21:51 top dovecot: imap-login: Login: user=<schmitta>,  
method=PLAIN, rip=::1, l ip=::1, secured
Jun 28 16:21:52 top dovecot: IMAP(schmitta): Disconnected
Jun 28 16:22:52 top dovecot: imap-login: Login: user=<schmitta>,  
method=PLAIN, rip=::1, l ip=::1, secured
Jun 28 16:22:54 top dovecot: IMAP(schmitta): Disconnected

It should also be noted that since I installed OS X.4.7, things seem  
to be working better.

Ah, nice to point this out. I just turned on "delay-newmail" as it's  
indicated to help with OS X.

I did not change anything about indexing.

Well, it seems that Mail.app copies or deletes messages one at a  
time, and sometimes wait for one minute between two messages. When  
this happens, going to another mailbox (to read messages, for  
instance) takes forever, and coming back to the mailbox where the  
messages were deleted shows them, until they get deleted on the  
server. I don't really know how to explain it differently (which is  
probably part of the problem as well ;-) ).

Thanks a lot,

Alan
