Comment 3 for bug 119899

Frank Widmaier: I am not seeing this problem in 1.3 Final or 1.4RC2; I created a
filter for 'User-Agent contains 1.3' and it worked as expected, for both newly
arrived mail and for running the filter manually (on the Sent folder).

Is this problem still an issue for you? Have you tried upgrading to 1.3 Final
or a 1.4 build?

Did you follow up on Bug 201244, as noted in comment 2? (Ignore the reference
to '20128', that is apparently a typo.) I'm curious if any of the details in
that report jibe with your experience.
