Message highlighting:



You should be able to do these things:



Create a new highlight



     Choose a scheme for highlighting messages that match a particular 
pattern (see below).



        1. Choose: Options -> Message Highlighting

        2. Choose: New

        3. Assign a name to your new highlight style

        4. Select a color for your highlight style

        5. Select a criterion for the highlighted message. The 
criterion matches, if the string is contained within the specified 
field. E.g. highlighting all messages coming from domain "foo.bar" 
would be done by selecting "from" within the combobox and then type 
"@foo.bar" into the pattern field. The match is case-insensitive, and 
will match a header containing the search string anywhere within it - 
but no wild cards or regular expressions.



Edit an existing highlight



     Make changes to a given highlight style.

Delete an existing hightlight



     Remove an existing highlight style from the set.
