I am running the latest ZA (11.0.768.00) with high security for the public domain. Even though I have Thunderbird as Super trusted and allow all in Application control, I cannot send to my SMTP server without switching off the AntiVirus. The email then goes OK. But if I switch AntiVirus back on then I get Connection to the SMTP server failed.
This must be a bug in ZoneAlarm, as AVS should not be effecting the firewall functionality like this, should it
