Personally I wouldn't worry about it, I use a postfix relay at our perimiter and it's our only MX record.
I take the approach that most MTAs retry over several days so it's got to be pretty damned bad before you should lose mail - bear in mind also that it would be bounced as undeliverable, it wouldn't just dissapear into a black hole. The problem I always found with using secondary MXs is that spammers love them, and usually you have little control over what mail they accept other than @yourdomain.com. regards, Paul -- Paul Hutchings Network Administrator, MIRA Ltd.
