Hi, After upgrading Dovecot from version 2.2.27 to 2.3.9.2, we are sporadically seeing lots of these errors in the error log on many of our servers: imap-login: Error: master(imap): net_connect_unix(imap) failed: Resource temporarily unavailable - http://wiki2.dovecot.org/SocketUnavailable The issue is causing significant delays and/or timeouts on login.

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.

If anyone was listening, the password was exposed. ls NO

I want to use service_count=0 and I'm starting with something like this : #default_process_limit = 100 #default_client_limit = 1000 service imap-login { [...] service_count = 0 process_min_avail = 8 vsz_limit = 1024M } -> Does it make sense to set a process_limit if

Hello, We've got a pretty substantial dovecot installation (versions 2.1.7 and 2.2.13 on the backends, but tested with 2.2.24 as well) and this is the relevant config snippet from 10-master.conf: --- default_process_limit = 1024 default_client_limit = 16384 [...] service imap { # Most of the memory goes to mmap()ing files. You may need to increase this # limit if you have huge

When I set this in master.conf: service imap { service_count = 5 } I see this error when two imap users log in: Nov 11 16:54:16 server dovecot[5432]: imap-login: Login: user=<user1>, method=PLAIN, rip=10.100.0.84, lip=10.80.0.163, pid=5573 Nov 11 16:54:31 server dovecot[5432]: imap-login: Login: user=<user2>, method=PLAIN, rip=::1, lip=::1, secured, pid=5573 Nov 11

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, 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?

We recently switched over mail servers to one running dovecot and postfix on RedHat Enterprise 6. The mail store is NFS on a NetApp filer, the index files are on local disk. We have about 6000 total active users, though not all of them access the system at the same time. All goes well for a while, then we start seeing errors like this in the log: dovecot: imap-login: Error:
