I am running Zarafa 7.0.6 in hosted mode with multiple domains. I'm running the IMAP service and connecting with Mail.app as supplied by OSX Lion.
Although the IMAP service works and receives mail, there is a constant flow of traffic at all times, which is not good when you have a bandwidth cap...
By contrast, my other IMAP servers (dovecot) use virtually no bandwidth when idle.
There doesn't seem to be anything in the logs, and before i turn off SSL and try to tcpdump to see whats going on i wanted to know if anyone else has experienced similar issues or knew of any configuration changes i can make to resolve it.
