The "@catwhisker.org" is probably being added my your mail transport.
Sendmail and postfix both have the misfeature of fully-qualifying
remotely generated strings on the header-from with your local domain.
Eg. if aol had the header-from line of:

        From: abuse team

It would be re-written as:

        From: abuse at catwhisker.org, team at catwhisker.org

This is way more helpful than I would like, but not quite annoying
enough (yet!) for me to get off my duff and hack the code.
