The Postfix policy protocol support is complete, but there is almost no semantics in-there. Similarly the support for Postfix tcp lookup maps is there. I did both mostly as a proof-of-concept, because most of the code is common with AM.PDP protocol support and was not difficult to add what was missing. See sub process_tcp_lookup_request for tcp lookups support (policy bank on the interface must specify protocol=>'TCP-LOOKUP'), and process_policy_request with postfix_policy, which can (syntactically) handle both the AM.PDP as well as the Postfix policy delegation support. The Postfix request is distinguished from AM.PDP request by the presence of the attribute: request=smtpd_access_policy' The problem with both is that these are pre-queue requests, with all the problems this drags along: amavisd would need to handle numerous sessions comparable to the number of smtpd services, which is normally by an order of magnitude larger than post-queue content filtering sessions. Heavy-weight calls to SA are mostly out of the question for any setup larger than a home or small office site. ...Which is the reason why I never pushed this beyond proof-of-concept. Experimentation may be interesting nevertheless. Mark ------------------------------------------------------------------------- Take Surveys. Earn Cash.
