Somehow, I created this topic under main Linux questions instead of ISPConfig. I hope someone can delete it there. Anyway, here is a copy Hello, I still have an old ISPConfig version 2.2.19 running on my box. Please don't ask to upgrade as everything running very smoothly and I don't want to mess anything up. Plus I have several Apache instances and Nginx. Reconfiguring everything would be a nightmare Anyway, on one of my primary domains names I have a catch-all email address (the administrator of the web-site). It receives close to 500+ email a day no some weird gibberish addresses like email@example.com where domain.com is my domain. If I disable catch-all - Postfix starts to send bounce emails back to those fake addresses it came from, which bounces back and etc. So I have to accept them via catch-all. Having said, it is a valid address where I get good mail - sorting every day through all that spam - I can't do it anymore Is there a way to configure Postfix to discard all catch-all emails and let valid defined accounts through? I thought about making some firstname.lastname@example.org a catch-all, but then I still have to clear it out every N days. I rather it just be discarded/deleted instantly. I would appreciate any help.
