So they've said to "add an A record anyway to the mail domain" They claim its an RFC requirement. To my mind , the servers should do an MX lookup and do the A record lookups on that host. Is there any such RFC compliance requirement ? Cheers Peter Lockhart To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
