Hello misc@opensmtpd.org, I just wrote a blogpost that explains how to configure OpenSMTPD as a mailrelay for (Debian based) servers.
I wanted to link it here in the hopes that somebody could find any mistakes I might have possibly made. Any feedback would be highly appreciated :) Here is the link: https://www.blunix.com/blog/secure-smtp-email-relay-on-debian-and-ubuntu-with-opensmtpd-instead-of-postfix.html with kind regards, Peter Thurner CEO Blunix GmbH -- Blunix GmbH Glogauer Straße 21 10999 Berlin Germany Web: https://www.blunix.com
