[Dovecot] v1.1 max connections per user

v1.1 has now:

# Maximum number of connections allowed for a user. The limits are enforced # separately for IMAP and POP3 connections, so you can move this setting # inside protocol {} to have separate settings for them. NOTE: The user names # are compared case-sensitively, so make sure your userdb returns usernames # always using the same casing so users can't bypass this limit! #mail_max_user_connections = 10

Is 10 a good default?

Currently new connections just fail authentication with a "Maximum number of connections exceeded" error message. v2.0 hopefully will instead disconnect the oldest idling connection with IMAP.
