Lynnejohn,

thanks for the log. We have looked on it with Vojtech and I am still testing this with ZoneAlarm. The “-ERR popgate unknown command” - although it might seem a bit strange - is perfectly normal. It just says that your mail server (pop at yahoo.com) does not support certain commands used by your mail client.

Also, what we can see there are two mail pickup retries (the interval is 5 minutes). First one ends with timeout, and the second one is in order. This means it is not some compatibility issue, invalid commands or invalid parsing, but rather some timing issue. The problematic connection (which later timeouts) comes through the ISAFE ZoneAlarm’s proxy - the process isafe.exe.

The only advice I can give you know is to try to switch off the E-mail protection in Zone Alaram and see if it helps. You can also turn off the transparent mail scanner in avast! (avast4.ini section [MailScanner], AutoRedirect=0) and configure Thunderbird support via PopWizard (ashPopWz.exe from Avast folder).

Lukas.
