Hello, I have configuration question. Running FreeBSD 9.0 / AMD64 / Dovecot 2.1.8 version and cannot get over 1024 processes. I`ve increased process_limit in imap and pop3 and still have messages in syslog like: maxproc limit exceeded by uid 89, please see tuning(7) and login.conf(5). Did I forget to increase some other value? System values are higher - kern.maxprocperuid: 8192 and kern.maxproc: 12288 I`d like to have more secure configuration > one process to one connection. Thanks for help. Tomas My conf...

I will be deploying Dovecot on OS X shortly. I am looking for clarification on the limits imposed by OS X and sysctl [kern.maxproc]. I understand that it is defaulting to 532, but can be raised to 2500. I believe the OS uses around 100 or so, plus I will have other processes and shells at times. Does Dovecot use one process per user logged in? I find Apple Mail uses about 4 IMAP connections per account. I am not sur...

...ied everything, including modifying startup script of dovecot to set ulimit -u 8192. Could it be some dovecot bug or dovecot<>freebsd bug?

But, problem becomes much worse when some emails are used in mailman, when it happens all 3 serves became really slow. iowait goes to 80. Does anyone have an idea how to slow

Hello, We are running Red Hat Enterprise Linux AS release 4 (Nahant Update 4) with OCFS2 for our mail servers. There are three nodes in the cluster with shared storage and OCFS2 filesystem on it. The filesystem is used for mail storage(using Maildir layout) and is accessed by smtpd, pop3 and imap processes(DOVECOT). The system works fine but when there are mailing lists the load increases

Hi, the lmtp service of our dovecot director installation quits with a segmentation fault if a lot of mails are simultaneously delivered. For example if the postfix mailqueue is filled (for whatever reason) and postqueue -f is run the lmtp service quits with a segmentation fault: Program terminated with signal 11, Segmentation fault. #0? o_stream_cork (stream=0x0)
