That's what I meant with "complex mail routing" :) The problem with having two passes through postfix in the mail routing chain is that you either run two separate postfix instances with independent configurations or you have to figure out a robust way to avoid loops. It can be done, it's just more difficult :) > Of course I can have postfix to skip amavisd for outgoing emails, but > then I guess I'll lose amavisd's automated whitelisting (the so-called > 'pen pal' feature). True. In my case that's not really a problem as we only have amavisd add a "spam level" header to messages; actually deleting spam is left to the clients, and most clients that support user-configurable spam policies and rulesets can do some sort of address whitelisting. andrea
