Such requirement is imho braindead. It is only applicable only on smaller systems since it doubles admin's work and is very error-prone. It also has side effect of changing envelope To: which can lead to more complicated filtering at recipient's side. Yes, it's apparently the only solution that will currently work for 100%, but there should be better solution(s) to this problem. e.g. being able to compare users in the same (virtual) user table even on backup MX even if the domain is not local. > Your primary MX should also be configured to accept all mail from your > backup, without any kind of filtering.

Well, even if mail from backup MX it will be filtered, backscatter from the MX should not be that problematic unless you use your backup MX for sending mail out. -- Matus UHLAR - fantomas, [email protected] ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.
