The proper Unix way. <3 > You. made. my. day :-) I'm glad that I resisted the pressure to implement milters and to push a ton of features in the daemon because the implementation is exactly what we wanted to achieve: fast, easy and secure. Took time but we are there. We lose the many milters that are available, but the simplicity allows a rewrite of any filter we need in a very short time, including maybe some milter interface on top of our implementation if someone feels like it.

Simple rewrite-from filter in awk
Hi, I was playing a bit with new proc filters and wrote a very simple filter for rewriting email address in both MAIL FROM command and From header with the specified email address... in just ~60 lines of AWK! https://github.com/jirutka/opensmtpd-filter-rewrite-from I'm really impressed how simple yet powerful is the new proc filter interface! The fact that you can implement a simple filter in fews lines of such limited language as AWK clearly proves the simplicity. No language-specific API and bindings, no complex formats or craps like gRPC, just plain old processes, stdin/stdout and simple line-oriented protocol with delimiter-separated fields. The proper Unix way. <3 Jakub signature.asc Description: OpenPGP digital signature

filter-senderscore for testing
Hello, I have written a second filter: https://github.com/poolpOrg/filter-senderscore Senderscore is the reputation scoring built by Return-Path which some of the Big Mailers Corp feedback into. It isn't bullet-proof but, while good reputations doesn't mean sender is good for real, bad reputations generally mean sender is bad for real. I'd appreciate some testing and reporting ;-) -- Gilles Chehade @poolpOrg https://www.poolp.orgpatreon: https://www.patreon.com/gilles
