I am finding that where a user has created a number of mail folders, Dovecot complains in the maillog "Maximum number of connections from user+IP exceeded". The default for Dovecot is 10. I have increased that to 15 - but I'm not sure I should just keep on increasing that.
Does the Usermin client have any way to limit the number of simultaneous IMAP connections?
