No, the way you explained the backup MX configuration I do not have it configured that way. But I did NOT say in the beginning that one of the servers was a backup server. This point came up only later and I guess X is not actually a backup. The point of my question was that if I have two separate severs X and Y, some of the domains that where on X before rebuilt are now on Y, so why is X getting the 'relaying denied' messages for those domains that are now on Y and should be handled by Y MX? I believe this is a rephrase of my original question which has been answered by you. > Am Do, den 24.06.2004 schrieb olga@xxxxxxxxxxxxxx um 16:40: > >> No, server X does not relay for the domains hosted on server Y (I do not >> have relay-domains file on X for for those domains that are on Y). >> Should >> I have it?
