Correct, that you would have to configure your secondary MX server named X to accept the domains of server Y for relaying to server Y. You do not need to create the users of Y on X as local users. You last sentence is incorrect: the lower priority MX record host is not without consequences! Imagine what happens: a foreign MTA speaks to the secondary MX server called X and tells him that he wants to pass him mail for userfoo@xxxxxxxxxxxxxxxxxxxxxxx What happens? Server X checks whether the domains is local - no, it is not - or to be relayed - no, no such instructions set, nor permissions for the foreign MTA to relay through server X. Consequence? The incoming mail is rejected with message "Relaying denied". You remember this sentence? ;) Alexander -- Alexander Dalloz | Enger, Germany | GPG key 1024D/ED695653 1999-07-13 Fedora GNU/Linux Core 2 (Tettnang) on Athlon CPU kernel 2.6.6-1.435 Serendipity 21:58:42 up 1 day, 20:36, load average: 0.41, 0.50, 0.37
