I’m trying to get mailcow to actually accept email from my proxmox hosts about status updates and such, I’m not very knowledgeable with how postfix/email in general works. I’m not sure if I need to add their IP addresses to a whitelist somewhere or set the hosts up to login as a specific user. I tried something for that and postfix logs just say “discarding EHLO keywords: CHUNKING” or other just disconnects.

Have something to say?

add the IP of the proxmox host to the “forwarding hosts” under System - Configuration - Options
disable spam checking.

    esackbauer also did that but still doesn’t work

    [unknown] postfix log just says “CONNECT FROM [ip address]” and then nothing

      then your config in proxmox is probably wrong. disable TLS and STARTTLS.
