We are very close to a new OpenBSD release. "You Have Installed OpenBSD. Now For The Daily Tasks." https://nxdomain.no/~peter/openbsd_installed_now_for_the_daily_tasks.html can help you prepare for the upgrade.
If you are using exim as your MTA (or any other non-base system MTA), "OpenSMTPD Is The Mail Server For The Future" https://nxdomain.no/~peter/time_for_opensmtpd.html contains useful pointers for a better mail future.

Repost for the Sunday crowd:
Migrating mail servers from exim to OpenSMTPD (smtpd) is fun and useful https://www.undeadly.org/cgi?action=article;sid=20260516064650 #openbsd #opensmtpd #smtpd #exim #email #smtp #mail #spam #antispam #greylisting #greytrapping #mailmigration
Are there people here that have examples of #opensmtpd filtering and/or adress rewriting ?
I am interested in two cases :
- want to block mail pretending to originate from my own domain (without breaking my own conf' ofc)
- want to rewrite all mail directed towards the dk tld so that it looks like originating from my dk domain (this is a simple rewrite of the address, I am legit owner and the MX is legit sender/receiver)
