In the category spammers will try anything that looks like an e-mail address I repeatedly find variations on this message in the system logs:

greenblatt sm-mta[12385]: n4RAsgSa012385: <8006@idefix.net>... No such user in domain

Where they get that idea? Simply: On the Asterisk podcast per telefoon page is a sip url for sip:8006@idefix.net. It looks like an e-mail address: spam it!
