I have two servers pointing to an NFS mounted mail spool with dovecot.? Since I recently switched from using Dovecot v1.X, I have been experiencing high CPU use with the two Dovecot servers. I am not certain why they are not well behaved.? Here is the configuration information. This configuration is currently running at a load average of 17. /usr/sbin/dovecot -n # 2.1.15:

I just upgraded my Ubuntu server from 11.10 to 12.04.1 and that upgraded Dovecot to 2.0.19. For some reason I'm getting a lot more (5 times) disconnect in IDLE and inactivity time outs. I'm using only IMAP with two users. Both users access the server from multiple devices, phone, tablet and desktop computer. I had previously set the max_userip_connections to 20 and rarely got the

Hi All, I need to import mailboxes into my Director NFS setup via one of my director proxy's as doing a direct dsync to the backend mailstores appears to giving me NFS locking issues. It looks like it may be possible to do this using doveadm listeners. I have setup doveadm listeners on a test proxy and backend mailstore. I am not sure how to make the dsync proxy through to the backend

Hi all, we have a problem about anvil, it seems that when we have a high load the dovecot stops to work. Sometimes it is sufficient to make a dovecot reload, but sometimes we have to restart it. These are the lines related to anvil in the dovecot.log: [root at secchia ~]# grep anvil /var/log/dovecot.log | more Oct 26 11:13:55 anvil: Error: net_accept() failed: Too many open files Oct 26

Hello In my installation the disable_plaintext_auth does not appear to take effect. I can see that the value is correct using doveconf -a but it doesn't change anything. Whenever attempting to log in using IMAP I get this: * BAD [ALERT] Plaintext authentication not allowed without SSL/TLS, but your client did it anyway. If anyone was listening, the password was exposed. ls NO

hi, one customer told us, that he has performance problem in his Thunderbird 3.1.9, while open his sent folder, which has round about 4000 mails in it, and 20k in his Inbox. For example TB, tries to sync the sent-folder list (over SSL) from the sent folder for now over 15min. In the log, I can't see any strange things, so for me, Dovecot works ok. Maybe, I should use better cache options?

Hi, Trying to get rawlog working on dovecot 2.2.31 configured as per https://wiki2.dovecot.org/Debugging/Rawlog but a) it doesnt appear to be loggin anything b) rawlog_dir which is supposed to be v2.2.26+ seems no where in site .. in fact complains about unknown variable So does rawlog still do anything ????

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, I'm migrating from one system to another. Both are Arch Linux, but copying the configurations and just modifying them for IP addresses and hostnames didn't work. Here's doveconf -n # 2.1.15: /etc/dovecot/dovecot.conf doveconf: Warning: service auth { client_limit=256 } is lower than required under max. load (3072) doveconf:

I recently upgraded my dovecot from 2.1 to 2.2, and when I started, I received this message: doveconf: Warning: service auth { client_limit=1000 } is lower than required under max. load (1024) Searching through my configs, I do not have 1024 set anywhere. In order to stop this I set client_limit=1024 in my auth{} block... this seemed odd that the defaults disagreed with each other. However,
