233165 - Flag filter not being applied automatically to incoming (IMAP) mail

Status: RESOLVED DUPLICATE of bug 184490

(MailNews Core :: Filters, defect)

Description

[Greg Colyer]

User-Agent:       
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.6) Gecko/20040113

I have a mail filter that flags certain messages. It works fine when run
manually using "Tools>Run Filters on Folder", but never seems to run
automatically on newly arrived messages or when Mozilla Mail starts up.

My Inbox is IMAP, in case that's relevant.

Cf. bug 182906, which seems to be the other way round (automatic application
works but manual application broken)!

Reproducible: Always
Steps to Reproduce:
1. Set up filter to flag matched messages
2. Receive mail

Actual Results:  
Nothing

Expected Results:  
Matched received messages should be flagged

Flagging messages via filter in a POP account is working OK for me, but it could 
be an IMAP problem.

Any other filters being run?  Is the message also being moved, or staying in the 
Inbox?

[Greg Colyer]

No other filters are being run, and no other action is being taken. The relevant
msgFilterRules.dat follows in its entirety (but with names changed for the
avoidance of spam):

version="8"
logging="yes"
name="abc def"
enabled="yes"
type="1"
action="Mark flagged"
condition="AND (\\"Delivered-To\\",is,[e-mail]) AND
(\\"Delivered-To\\",isn't,[e-mail])"

In case it's of any help:

1. The rule itself may actually be broken -- it's intended to flag messages
delivered to "abc" except those redirected from "def", and I haven't yet
received all the necessary kinds of message to test it fully -- but the point of
this bug report is only that it doesn't run automatically. When run manually, it
does flag messages sent directly to "abc".

2. Delivered-To is a custom field (created using the Mozilla UI) that can occur
multiple times in a message, like Received. It's added by MTAs (e.g. qmail).

I believe the problem is not with your selecting Flag, but with your 
custom-header criterion of "Delivered-To" -- per the dupe, custom headers are 
not filterable under IMAP.

Since reporting the bug I've deleted the given flag rule but have created
another, also based on the custom Deliver-To header, which works fine. Per the
other bugs, this could be caused by a change (unknown to me) at the IMAP server.
However, if the problem is that the custom headers have sometimes not been
downloaded, would the filter have run successfully from the tools menu?

Depending on the answer, this bug may need reopening. However, I'm not reopening
it because I don't even see the original problem now! (I haven't changed build.)
