Re: [Declude.JunkMail] Filtering on a header

[R. Scott Perry]

When you are attempting to filter on a header for example this header

X-Mailer: The Bat! (v1.52f) Business

Would the following line in my filter file work
HEADERS 10      CONTAINS X-Mailer: The Bat! (v1.52f) Business

Or should I use

HEADERS 10      IS X-Mailer: The Bat! (v1.52f) Business

Is their any real difference in efficiency between IS and CONTAINS in
the above example?

Only the first one will work.

The key here is that Declude JunkMail is looking at the *entire* headers (it isn't going through each one, line-by-line). So "IS" would only work if you had the entire headers in the filter.
