Well, the CNAME is breaking a couple of rules here: - never have a CNAME and one or more other records on the same hostname - never send mail to a CNAME - never have a MX be a CNAME itself. I think the problems with the A record are related to nameserver cache refresh timeouts. Also, sendmail indeed does rewriting on a CNAME, which might be an explanation. Actually, qmail does that too. It's an RFC rule.
