Then please give me the credit by including an attribution line for
the quoted text. This thread is about dealing with Usenet annoyances,
so it's ironic that you have a mildly annoying habit yourself.

No. That would drop any article whose Message-ID contained any
character other than lower-case a-z, including "@" - IOW, it would
drop all articles.

Try
* drop Message-ID:.*@[^a-z]+>.*

This should match a string of characters, none of which is a
lower-case letter, between "@" and ">".

The final ".*" takes account of any trailing white space after the
Message-ID's closing angle-bracket: " *", "[ ]*" or "s*" would do so
more efficiently, but I don't know which, if any, would work with
NewsProxy, since I don't know what kind of regular expressions it
uses. (And I can't install it myself, since I'd have to install
Windows first.)
