Which solution do you use? > Does it permit to define alternative hosts for antivir/antispam? as for the a/a server, we use postfix+various dnsbl+amavis+clamav (postfix patched for quota support), while the "standard" server is the same without dnsbl and all antivirus things. My idea is to use two servers, ie for the a/a, with round robin, to be able to balance the load because I'm sure that in a few months even a more powerful server reache the limit, without changing anything else in customers configurations, dns zones, and so on. -- Bye Enrico Elefante: un topolino progettato secondo le indicazioni del governo. -- Robert Heinlein
