[Dovecot] troubles with 1.1.8 and squirrelmail over HTTPS
Hello
I noticed a problem after upgrading to 1.1.8
Users that access to their mailboxes using webmail squirrelmail and HTTPS using HTTP seems to work correctly but it not safe enough ...
There is an error message saying the imap server send a BYE command ...
I downgraded our Dovecot server to 1.1.7 then it works again ...
Does somebody has the same problem ?

Communication between Dovecot and Squirrelmail has nothing to do with communication between Squirrelmail/Apache and the end user.
Did you also upgrade Squirrelmail or its config files in the process?

Like Tom said, the http vs https difference shouldn't be visible to Dovecot. Anyway do you see any errors in Dovecot's log files? http://wiki.dovecot.org/Logging

And what version of SM you are using. We use the latest and have no issues, and you need to tell us what said the error, SM via php display, or apache or what.

Well ... I apologize !
I finally found the problem but it sounds a bit strange
I had to increase the max_mail_processes to 8192 to have a functionnal IMAP server with normal clients AND squirrelmail clients
8192 sounds enormous to me , any infos welcome !
the machine run Debian etch 64 bits , dovecot has been re-compiled on the machine. it is an IBM X3650 with 7Gb of RAM.

How many imap processes have you running typically?

Did you found any explaination to this problem ? Do you think it could be a Linux problem or a Dovecot problem ? Thanks

If the problem had to do with max_mail_processes, Dovecot would have logged:
"Maximum number of mail processes exceeded (see max_mail_processes setting)"
Did it? If you can't find that from logs, then either you're not looking at the right logs (http://wiki.dovecot.org/Logging) or changing the max_mail_processes didn't actually do anything and instead simply restarting Dovecot fixed it (or the original problem just happened to go away for some other reason).
