Re: [exim] How to filter 'negatively' ?

hello Philip,

Just making sure I'm correctly understanding what you've said;

let's imagine there is a header in certain mails called
List-Subscribe:

are you saying that I would need to make a filter as shown below :

if $message_headers does not contain "List-Subscribe:"
then
...

?

If I've got that right then this has indeed taught me something, as I
thought up to now that $message_headers would only look at the _content_
of message headers, and indeed specifically only the headers to: from:
subject: and reply-to:

Was my assumption there wrong on all counts ?

Thanks for the anticipated extra confirmation here,
Lee
