Hi! I upgraded the 2.2 packages today (from 2:2.2.28-1~auto+5 to 2:2.2.28-1~auto+8) I now I'm getting an error: Mar 20 13:25:58 mproxy dovecot: auth: Error: imapc(email.charite.de:993): Couldn't initialize SSL context: Can't verify remote server certs without trusted CAs (ssl_client_ca_* settings) I checked, and alas, I had ssl_client_ca_dir = ssl_client_ca_file = So I set:

During norml operation this morning we're seeing a significantly increased load on the IMAP server (factor 5, from 5 to 25). Does dovecot need to rebuild index files or perform other IO intensive operations after the upgrade? We're using Maildir Our monitoring shows increased "system" time. We're runnign fewer processes, the IO rate ist identical to yesterday, memory usage

Due to the ongoing performance issues with 2.0.x I switched back to 1.2.15 yesterday evening, with no changes to the machine or my users. (I migrated from 1.2.15 to 2.0.x by converting the existing config) Today, we have MUCH LESS load, with the same number of logins/min. I cannot say what exactly causes this immense increase in load, but one observation is that the time spent in system() has

It is misleading, I know, but it does say file. =) Makes no difference: # doveconf |fgrep ssl_client_ca ssl_client_ca_dir = ssl_client_ca_file = /etc/ssl/certs/ca-certificates.crt and with
