How to filter an email with a "reply to" line in the header?

In filtering certain junk emails I've noticed the 'From' email address varies but there is a constant email address in another line 'Reply to'. I tried to add a custom tag but 'Reply To' causes an error message. If I could filter the 'Reply To' line I could get rid of a major source of junk email.

Thanks Matt & Zenos. It turns out the answer is "Reply-To" with no colon.

put a colon after Reply To: all header fields end in a colon To: From: etc.

I still get an Alert message "The header you entered contains an invalid character, such as ':', a non-printable character, a non-ascii character, or an eight bit ascii character. Please remove the invalid character and try again." So in 'Reply To:' what would be the invalid character?

I don't think header field names can include spaces. I believe it needs to be "Reply-To:"

My own filter criterion drop-down includes a "Reply-To" option, but I may have put it there myself, or it may be there courtesy of FiltaQuilla.
