[imapfilter-devel] Imapfilter sometimes doesn't filter

[Ezsra McDonald]

David,
I saw a similar problem even in the versions before imapfilter 1.0. My
observation was that if a imapfilter was executed and before it was
complete a message was delivered into INBOX the message might get
filtered by the wrong filter.

Say I have these filters:

1. Filter all mail from friend at yahoo.com to folder friends.
2. Move all remaining mail to Junk folder.

If imapfilter is executed and a message is delivered from
friend at yahoo.com between the after the execution of filter 1 but before
execution of filter 2 it would get filed into the junk folder.

My solution was to move all mail from INBOX to a folder named ztmp. This
way the folder contents would not change during the filtering process. I
then ran all my filters on the contents of the ztmp folder so I would
not have this problem.
