[Dovecot] IMAP extensions & their meanings
by Jerry 01 Apr '10

01 Apr '10

I know that is is not really a Dovecot problem; however, I was wondering where I could get a complete list of the terms used in the 'capability' line. I have not had any success in finding out what things like "XLIST" refer to. I don't believe that is one that Dovecot uses; however, I have seen it with other IMAP servers, plus lots of other flags that I do not understand. I tried Googling but only got a few sporadic and basically useless answers. Thanks! -- Jerry Dovecot.user(a)seibercom.net Disclaimer: off-list followups get on-list replies or get ignored.

Ola Daniel, thanks for the idea, but actually within the config file the settings are not within the auth default section, its just shown that way from the output of dovecot -n cheers Andy.

The client is always Thunderbird 3.0.3+, but from different systems. It does terminate without any error message in the logs when I exit Thunderbird. Now testing without zlib... Bernhard
