Unless you have a really good reason, you'd be much better off just losing the MX2, and let smtp work as designed (retries if the primary is down)... The only time I personally would try to keep a secondary is if my primary was prone to going down for extended lengths of time - but of course it woul dbe better to solve that problem (worst case, host with someone more reliable) than put a band-aid on it... -- Best regards, Charles
