@tgeusch I switched from #postfix to #openSMTPD about a year ago, and from #mailman3 to #mlmmj . Both are less flexible (powerful), but the simplified configuration is definitely worth it for my relatively simple needs. I kept #rspamd for DKIM and filtering, and it all works quite well.

Question for those who #selfhost their email servers - has anyone migrated from #postfix to #openSMTPD?

I've been running Postfix for more than a decade on the primary MX, but it frankly feels overkill for a relatively simple multi-domain setup for essentially just hosting my family's email.

I'm already running openSMTPD on #OpenBSD on my secondary, so I've got some limited experience with it.

Nothing against Postfix, it just feels that with my setup I'm using an 18 wheeler to transport a case of beer...

CVS somehow started sending email to my phone's email address. I don't want them to email my phone directly, so I tried unsubscribing, but that was evidently fruitless.

In puzzling over what to do, I realized that while I can't have Postfix's header_checks match two different headers - my first hope - their headers all include a Received line from an internal MTA that happens to embed the target email address!

Jeg har selvhostet mailserver i årtier for familien, venner, forskellige foreninger.

Det har aldrig været en dans på roser. Når det virker, er det rart. Når det ikke virker, så er det meget u-rart.

Er netop faldet over mail-in-a-box som gør det muligt at hoste en mailserver nærmest uden besvær, ser det ud til. Er der nogen der har erfaringer?

For some odd reason, I at one point disabled #DKIM signatures on outgoing e-mail on my #Postfix / #OpenDKIM setup. With the #DEMARC and #SPF policies still in place, some of the e-mail being relayed, including that of #MSTDNDK must unfortunately have been rejected at the destination mail servers. The issue is fixed now.

Shoutout to https://mailtested.com - it came in handy when testing if signatures were in place! :-)

Q - Who is still running #postfix sender address verification? https://www.postfix.org/ADDRESS_VERIFICATION_README.html / seems there are more and more "misconfigured" servers out there that I would need to whitelist to actually run proper sender's address verification. What's your take on this? Any useful feedback or tips? #SMTP

Postfix experts: can I use nginx to reverse proxy email, or should I use postfix to do that? I would like to eventually move my email to a home server, behind a Wireguard VPN, if that's even feasible.
