Indeed, a single MX is sufficient in most cases because the SMTP protocol already is quite fault tolerant as it is. SMTP relays are supposed to keep trying to send messages for a few days if the dedicated MX cannot be contacted. Personally, I have been using the "single MX" approach for several years for a row of domains, and I've had no problems with it even though there have been some MX downtimes. ------------------------------------------------------- This SF.net email is sponsored by: IT Product Guide on ITManagersJournal Use IT products in your business?
