Cancel that advice. Timo did a change that should make changing the
timeout by hand unnecessary. If you can, try running Dovecot
with this patch http://hg.dovecot.org/dovecot-2.2/rev/647162da8423.
There should be no time outs, even for large mails.

Do you get any error messages, when there is a timeout?

Have tested with the patch from Timo ( applied to 2.2.13 version ) and 
have successfully synchronized with
a mail  double the size of the mail that causes trouble before. So the 
changes looks correct.
But i have not tested that the timeout occured if the link is down or 
broken.


Thanks a lot for the quick response. Very helpful.

SASL LOGIN : connection to server lost with more than 10 simulatneaous postfix smtps

2014-09-04 Thread Ve (HOME) 

Hi All,

I have a problem with SASL authentification from postfix when more than 
10 mails is sent from the same user simultaneously
Postfix abort connection (  Connection lost to authentication server ). 
Dovecot log after the postfix error an error about

connection lost also ( read EOF )

I don't seem to find a parameter for a maximum of connection for the 
auth process ( ther's one for imap, pop, .. ) but none for auth.


Do you have an idea of a way to solve this problem or to have better 
information ?

Replication problem

2014-08-19 Thread Ve (HOME) 

Hi,

I'm using mdbox and replication. Due to configuration error 
synchronization was not able to be done last week. Since then
the problem has been corrected but synchronisation for some mailbox 
always failed in I/O stalled timeout for 600 seconds.


The link between the two servers is quite slow and multiple sync are 
done in parallel leading to congested link.


I can't replicate with rsync as change in the mdbox has been done on the 
two servers to get back to a working state.


What do you think could be done to resynchronized the two dovecot 
server. Another question is what is this timeout ? Timeout of 
communication i.e no data received during 600 seconds ( to me that looks 
unlikely ) or 600 seconds for doing the full sync or 600 seconds for one 
mail sync.


Thanks for any help.

Regards,

Vincent
