I have recently installed new untangle firewalls ( untangle.com) in Bridge mode at two office locations. Both offices collect mail from a Fedora 9, postfix,dovecot server at location #1. Since the install of the untangles i have been plagued by Thunderbird Errors while trying to POP email.
The error says "RETR" command failed. If the user logs into the webmail (Squirrelmail) on the mail server and cleans out his inbox by deleting all existing mail, T-Bird starts operating again. This error has repeated itself without a pattern i can identify dozens of time over the last few weeks.
No other email client displays errors.
T-Bird = 2.0.0.16 on XP or Vista OS UT = 5.3.0~svn20080624r1690release5.3-1sarge Dovecot = Version : 1.0.15, Release : 10.fc9 Postfix = Version : 2.5.1, Release : 2.fc9

Has anyone else seen this issue with T-Bird ?
