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

If you are a #postfix user and think what is described in this HOWTO http://www.postfix.org/ADDRESS_VERIFICATION_README.html[1] is useful, I can tell you:

IT IS NOT.

Longer version: https://nxdomain.no/~peter/twenty-plus_years_on_smtp_callbacks_are_still_pointless.html

[1] a more appropriate title would be "Further punishing joejob targets HOWTO"

I added a few more translations of the phrase "The rest is trash" to the spamtraps at https://nxdomain.no/~peter/traplist.shtml (see https://nxdomain.no/~peter/the_rest_is_trash.html or https://bsdly.blogspot.com/2026/02/the-rest-is-trash.html).

If you want further translations added, please let me know (with translation in your message).

The list without wrapper text is available as https://www.bsdly.net/~peter/sortlist.txt (BIG! -- 22975800 entries as of right now, will increase)

"The Rest Is Trash"

We are now halfway through the nineteenth year of greytrapping, still tracking and collecting from the wealth of imbecility out there
