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

Dovecot
tail -f maillog | grep 'username'

Has anyone else seen this issue with T-Bird ?
