For long-term scalability/flexibility, I personally add an Email Server Alias of mail.domain.com, and have the domain's MX record point to mail.domain.com (also need an A record for mail.domain.com pointing to same IP as www.domain.com). Then, if I ever need to move my mail server, all I have to do is change the A record for mail.domain.com to point to a new server...
Do you then have TWO MX records for the domain? Like this? domain.com > mail.domain.com mail.domain.com > mail.domain.com If so, should one also add an MX record for www.domain.com? -- - James Dean Young www.sundream.com jd@xxxxxxxxxxxx"Sometimes you get shown the light, in the strangest of places if you look at it right"
