Cnames are effectively the same as the record they point to. You probably intend for any mail sent to user at wa4phy.net to be sent to the primary/secondary MX receivers you specified, but as a side effect of the CNAME, mail sent to user at www.wa4phy.net or user at ftp.wa4phy.net would go to the same places because the MX records also apply to them. It isn't likely to matter in this case, but someday you might want to direct mail to those addresses elsewhere and be surprised that you can't give them a different MX. Or if you actually want mail to go to those addresses you might be surprised when they sometimes hit the secondary MX that might not be configured for them. -- Les Mikesell lesmikesell at gmail.com
