GNOME Evolution Tip: Filter according to Reply-To Field
=======================================================
I have subscribed to TAU (Tel Aviv University) Alumni Organization.
Sometimes, I receive e-mails from them. I have decided to organize my
emails, and move relevant e-mails to another folder.
Recently, I started receiving mails to my Incoming Mail folder because
the e-mail address of the organization was in the "Reply To" field.
So, I e-mailed the following question to the Evolution mailing list:

  How do I filter a message according to the "Reply To" field?

I received a response shortly. 

  There's a filter condition "Specific Header" in which you can specify
  any header.

I tried the condition before, but did it the wrong way. In addition I found 
that the header is "Reply-to" by clicking <ctrl>+<shift>+M to compose a
new message. Then From the new message window, clicking View, seeing in the
drop down list that there is a 'Reply-To" field. Yep, that's the header.

So, I added it. Now it's time to document the solution.
