Hi, new OpenSMTPD user here. I did (and still do) administrate Debian with Exim for several years and wanted to try something different.
So I got myself a server with OpenBSD and OpenSMTPD. So far I am impressed that a fully functional and secure SMTP server can be configured with such a small config file:) Congrats to the devs. Now that basic functionality is accomplished I want to try more. Of course I found config snippets here and there, but I think some parts of the puzzle are still missing and I still can't see the whole picture. Additionally most of the examples online are in the old syntax format. 1. Spam checking: I know there are solutions which do include spamd, Spamassasin and pf. Whats the best practice and what about rspamd? 2. SPF checking: I think, this should also be done by the spam filter? 3. Sender Rewriting Scheme (SRS): SPF is breaking mail forwarding in some cases, and the solution to this is SRS. How can this be done with OpenSMTPD? Kind regards, Henry
