The server responds with the 3 records in a (usually) random order. It's up to the MTA to figure out preference. For instance for me, it changes for pretty much every query: kluge.net. 86400 IN MX 10 mail.bblisa.org. kluge.net. 86400 IN MX 10 bugzilla.spamassassin.org. kluge.net. 86400 IN MX 5 eclectic.kluge.net. kluge.net. 86400 IN MX 10 bugzilla.spamassassin.org. kluge.net. 86400 IN MX 5 eclectic.kluge.net. kluge.net. 86400 IN MX 10 mail.bblisa.org. kluge.net. 86400 IN MX 5 eclectic.kluge.net. kluge.net. 86400 IN MX 10 mail.bblisa.org. kluge.net. 86400 IN MX 10 bugzilla.spamassassin.org. but MTAs know they should take the 5, then either of the 10s. -- Theo Van Dinter, [EMAIL PROTECTED]/[EMAIL PROTECTED] Systems Administrator, bblisa.org/kluge.net
