Either by using DNS round robin for amavis.domain.tld with IP1, IP2, IP3 or by using MX records with three entries for amavis.domain.tld as described above > > With > > $forward_method = 'smtp:*:10025'; > > in amavisd.conf amavis will forward the scanned message back > > to the originating postfix server and you can share several > > amavis installations on more than one SMTP gateway making it > > possible to use also round robin for your SMTP gateways. > > My only fear is that a such approach could icrease drastically the DMZ > network traffic.. :-( You're simply doubling the number of mails transferred within your network. As long as your network load isn't already at 50% this shouldn't be a problem. ------------------------------------------------------------------------- Check out the new SourceForge.net Marketplace.
