I know you've resolved this and that the issue was that
header_filter_rules are processed way before the subject_prefix is added
so you didn't want the '\[.*\]'part of the pattern, but I'm confused by
the '[\s\+]*' part of the pattern which says match 0 or more occurrences
of the character class consisting of any white space character (\s) and
the plus sign (either \+ or just + would be equivalent here, + loses its
special meaning inside []).
So, is [\s\+]* a typo or did you just mean \s+ or \s*?
The [\s\+]* was deliberate. Most of our lists but the list name in
brackets ('[', ']'), however, we have a few lists that are members of
another list. For those lists the list subject prefix is a plus-sign
('+'). For example, we have a student list that has the [Student]
prefix when the messages go out. Faculty and staff are not members of
the list and don't receive those messages. Yet, there are a few faculty
and staff who have an interest in seeing the messages so those
faculty/staff are put on a "listening" list which is a member of the
student list. When a message goes to the student list, the prefix
[Student] is added to the subject line. The message is then sent to the
"listening" list and it adds its own subject prefix. Instead of having
'[Student-Listen][Student]' show in the subject line, I changed it to a
'+'. The long and short of it is that I was trying to match both types
of lines and the [\s\+]* was the bit for matching the "listening" list's
subject prefix.
Also, can any of the sender/recipient filters cause the message to bypass the
spam filters? The message pipeline is unchanged.
No. header_filter_rules are processed by SpamDetect which is the first
module in the pipeline. As you discovered, the CookHeaders module which
adds the subject_prefix comes much later, and the sender/recipient
filters are processed by Moderate which also comes later.
Great information to know, thanks.
The only issue I have now is the boss wants to be able to send a reject
message if a message is rejected when it matches a rule. The only
option I have is to hold the message and let the moderator send the
rejection notice. And since, the header rule is for our global lists, I
am the lucky moderator.
Thanks for all the great help,
Chris
