Hello everyone,
I'm scratching my head with a curiosity. I want to play a bit with a filter during the SMTP connection. I don't want to use amavis nor spamassassin in this case, but I want something much faster and less resource intensive. 1. I run my own public Pyzor sever (and Redis cache) with 18K fingerprints so far. 2. I want to send the content to a TCP where a light filter will use Pyzor client in order to accept or reject the message. I read the documentation back and forth and cover some tests already in the last 2 weeks (milter, filter, proxy, smtpd_end_of_data_restrictions, check_policy_service, spawn). I know only bash which is a dead end. Would be easy for me to use a script and Pipe, but I will not be able to respond with a Reject, Defer, Redirect, OK or Hold. Not to mention if the disk is full, the messages will be lost. queue_minfree might save the day here. So far, I think would be nice to have a way similar to check_policy_service, but which would send DATA too. I think Milter/Filter are the right directions, but I can't find a way to combine them with spawn as I did with check_policy_service. Any thoughts, suggestions, advices? Thank you. Marius.
