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 :-)
