David,
Just an outside guess. 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...
