Hello, I have two Postfix inbound servers which serve multiple domain and I'd like to accept 20 Mb email for all domain except one (I want 10 Mb limit for this one). In main.cf I set message_size_limit = 20971520 and I use a policy server (postfwd) to check the recipient and the mail size. I configured postfwd that way : when the recipient belongs to the 10Mb domain and the size attribute is over 10 MB, then return a 5xx error. In most case, it works but sometime it doesn't and I don't understand why and how to debug…
As far as I understand, the documentation says that the size attribute is set by the sender. So the size is not computed by Postfix nor the policy server and I have to rely on information (badly) sent by remote mail servers.. Am I right ? Is there a better solution to achieve my goal ? Thanks for your help. Alexandre
