I'm not really sure what the question is, but it's a problem that you can't do much about - I certainly wouldn't take the time and trouble to migrate to a different domain name as it could just as easily happen again.
It's a PITA but so long as you can show anyone who emails you that it didn't originate from your servers that's about as good as it gets AFAIK. regards, Paul -- Paul Hutchings Network Administrator, MIRA Ltd.
