Comment 57 for bug 119899

To Hartman:

I had no problems with 1.5.0.12 with after fact custom IMAP filters or any of
the 1.5 versions of Thunderbird.

All of my problems with filters started after my upgrade to 2.0.

If I am reading what has taken place, is that filters work on the local
database because of broken IMAP servers -- making the rest of us suffer because
of this... people are still complaining about this issue. I was using Outlook
Express and Outlook 98 until I found Thunderbird and it is filtering
capacity... I now could use one product for reading and filtering email --
Outlook Express will filter IMAP from one IMAP account to another (move from
one IMAP server to another server or account on the same server). Outlook will
do such filter but will not display images inline. Thunderbird does both and
until recently did it very efficiently. Now this issue with filtering being
broken to me has almost made it worth going back to an older version that does
work and forgo the new features of Thunderbird until this is fixed. -- The fix
is simple: include all headers in the local DB.

Turn on offline access would do this but it not only caches the headers, it
caches the body as well and if disk space wasn't a problem this would be a good
solution.
