Hello, as described in [253363], login_process_size of 32M is not enough on 64-bit versions of Fedora and RHEL (and possibly other distributions as well). [253363] https://bugzilla.redhat.com/show_bug.cgi?id=253363 As I understand it, there's an intersegment gap between read-only/executable and writable segments of shared libs. That's prob...

Any suggestions on sizing login_process_size and login_processes_count for a server expected to be doing 100 to 200 simultaneous connections? Is there a way to separate login_processes_count between imap and pop? I would like to have at least 50 imap processes ready, but we rarely have any more than 5 to 10 pop connections. Would be a sha...

Hi, I am trying to use the command: doveconf -n -c dovecot-1.conf > dovecot-2.conf to upgrade my dovecot.conf file, but it fails (see below). Judging from the message that vsz_limit is the new setting for login_process_size, I have retried using login_process_size=256 rather than login_process_size=64 (which was the initial value), but the error persists. Please advise. Thanks, Nick Output of "doveconf -n -c" command: ======================================================================================...

I have a Dovecot server set up as a proxy and getting a ton of these errors, but I'm not sure where to begin troubleshooting it. I'm hearing frequently that Outlook users who use IMAP with SSL are getting disconnected often as a result. Any suggestions?...

After updating my system from OpenSSL 0.9.8j to 0.9.8k Dovecot has stopped functioning properly with TLS sessions. The version of Dovecot does not seem to matter as I tried 1.1.11 - 1.1.14. Other programs using SSL/TLS such as Postfix and lightty still work fine when built with the newer release of OpenSSL. The IMAP client doesn't matter. For the time being I have gone back to .13 linked

Hey guys, does somebody get dovecot work under cygwin? The compilation finish without any problems. But after trying to run dovecot i got this in my log: dovecot: Nov 17 02:40:18 Info: Dovecot v1.0.7 starting up dovecot: Nov 17 02:40:19 Fatal: setrlimit(RLIMIT_DATA, 256): Invalid argument dovecot: Nov 17 02:40:19 Error: Auth process died too early - shutting down dovecot: Nov 17 02:40:19 Error:

..., eudora, thunderbird Unix/Linux: evolution, thunderbird, pine, mutt Web: squirrelmail Apart from the example configuration file, I can't find any guides for optimal values to use for dovecot's many configuration options.

...rating from a windows server and i have very few stats as to what our current concurrent usage stats are other than about 50,000 active users and 90,000 email messages a day inbound 20,000 outbound. Anyone got some tips for tuning dovecot to handle this load? Below is my config - do the values of login_process_size etc sound correct? Also my logs seem to be written out as root which seems kind of scary do how do I / should I have these written out by the dovecot user. Any feedback greatfully accepted.

...= 256. A common enough heavy load has something like 275 unique users accessing imap and 600 imapd processes. Suggestions? I'm beginning with no SSL, KISS. b) If I set login_process_per_connection =no, would the number of users accessing imap be the same as the number of imapd sessions? c) login_process_size is confusing/intriguing. If there are 500 processes, the default of 32MB means 16GB (the box has 12GB). OTOH, what about the big players with a 400 MB inbox...will they be able to open their inbox with the default d) login_max_connections ditto...I shouldn't think that an individual user...

Hi, I'm running dovecot on an Ubuntu server (1:1.0.5-1ubuntu2). Dovecot provides pop3, imap, and sasl to postfix. The setup works quite nicely, however I do have one error that shows up repeatedly in my dovecot.log. <snip> dovecot: 2007-12-12 09:29:06 Error: child 32765 (login) killed with signal 9 dovecot: 2007-12-12 09:29:06 Error: child 18039 (login) killed with signal 9 dovecot:
