Check the number of dovecot processes currently running on the host for any given user. (with imap access via desktop, laptop, tablet, iphone each can open 2+ session which easily exceed the default 10 allowed) On all my dovecot installs, I've had to increase the number of simultaneous connections to 30. Otherwise, dovecot just refuses to allow a connection giving an ("Unknown error"). To increase the max allowed connections, edit /etc/dovecot/dovecot.conf and add the following: protocol imap { mail_max_userip_connections = 30 } I've been bitten by this more than once -- I don't have excess hair to pull out anymore... -- David C.
