[Dovecot] Multiple Concurrent IMAP Connections For Same User

[Nigel Webber]

I should have mentioned that this is not iPhone specific, the same 
behaviour may be observed for 2 simultanious connections from 2 separate 
machines running Thunderbird.

TLS/SSL is used on both.

dovecot config file below:
