This file seems to be good for a private test server but for real world tasks, it simply won't work as you have seen. Using the original conf files are a better choice IMHO, like the prefork example: https://github.com/cyrusimap/cyrus-imapd/blob/master/doc/examples/cyrus_conf/prefork.conf Regards, Simon > > When I checked it before, I had 120 imapd process running and 125 > connections (netstat -tapn | grep imap). > > Now I have 121 processes and 97 connections. > > I will report here. > > Thanks! > István > > > > 2022. 11. 15, kedd keltezéssel 12.53-kor Ivan Kuznetsov ezt írta: >> Hello >> >> It can be a lack of available IMAP handlers.
