I could write a perl filter to spot and excise such messages

same parsing of messages that MHonArc does it would seem logical to do it
in one place. It would seem that the mechanism you have implemented to
ignore messages with the no-archive flag set would be the candidate for me
to look at.
I've thought about it. I have been considering what the best approach
will be. Maybe something like:
<MsgExcludeFilter>
/^Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA/m;
</MsgExcludeFilter>
Basically, the resource allows you to use Perl code to determine if a
message should be skipped. $_ will contain the raw message header. If
MSGEXCLUDEFILTER evaulates to a true value, the message will be
excluded.
Comments?
I like this: you could do other useful things such as:
/^Subject: .*(money fast|XXX sex|business opportunity|your web site|test
message|unsubscribe)/im
(Couldn't excluding messages with the X-no-archive header set have
been done this way too?)
What might be useful would be a way of ANDing and ORing
expressions to match on e.g.
<MsgExcludeFilter>
<!-- implicit OR: exclude if any of following rules matches -->
<FilterRule>
/^Subject: DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA/m;
</FilterRule>
<FilterRule>
/^Subject: unsubscribe/im
</FilterRule>
<FilterRule>
/^Subject: test message/im
</FilterRule>
<FilterRule>
<!-- implicit AND: this rule matches if both of following
regexps match -->
/^From: \w+\@(aol|hotmail)\.com/im
/^Subject: .*(money|opportunity|your web)/im
</FilterRule>
</MsgExcludeFilter>
This still seems a bit clunky to me: I have a feeling it could be
made more elegant and expressive, but I can't see how .... and I don't
know how any of this would be to implement.
Anyway, that's my 0.02 ECUs worth for today :-)
