Oh dear. Don't tell me fetchmail is looking up the address, finding the CNAME and rewriting the address to be that which the CNAME points to?
Ah, I should have read the rest of the thread before sending my previous comment l-) Perhaps the 'for' stuff is a red herring after all.
Mixing CNAMEs and mail delivery is IMO hopelessly optimistic, and rewriting based on CNAMEs has been happening in some places for years, on the basis of things like RFC1123 5.2.2. Just don't do it.
