They don't need to have an MX record; an A record will do. roaringpenguin.com, for example, has an A record. If roaringpenguin.com had no MX records, then mail for [EMAIL PROTECTED] would go to the A record. > What needs to be in place is a valid return path for the mail that is > generated.

No; if there's no MX record for "example.com", then the A record for "example.com" will be used, if it exists. If no A record exists either, then it will be impossible to mail [EMAIL PROTECTED] -- David. _______________________________________________ Visit http://www.mimedefang.org and http://www.canit.ca MIMEDefang mailing list [email protected] http://lists.roaringpenguin.com/mailman/listinfo/mimedefang
