Has anyone already encountered a smtp processing bug that can impersonate the real sender server-side ?
We had a surge of phish mails this morning (distributed source IPs, multiple subjects/content, envelope domain with SPF pass from Japan).
The envelope "from" was in this exact form :
FROM: INFO [0552] <[email protected]>
and bounces are sent to INFO@<DomainFromRecipient> instead of [email protected]. If the phish mail was targeted at [email protected] -which supposedly doesn't exist- the bounce is sent to [email protected].
It brings back memories from a few years ago when a bug in most mail client softwares allowed something similar, but client-side and not server-side like what we see here.

Part 11-2 of our SMT: Digital Devil Saga livestream is now on YouTube. We make it to the top of Nirvana after numerous puzzles (and a severe lack of save points). Then it's another boss fight, and a point of no return.

Part 11-1 of our SMT: Digital Devil Saga livestream is now up YouTube. The climb of Nirvana continues. As we make it closer to the top of the tower, there's a boss fight. It's become clear Sera doesn't want to see the group, but we press on anyway.

Tonight I'll be livestreaming more SMT: Digital Devil Saga for @damagecontrolblog on Twitch. The ascent of Nirvana continues, and I probably have some boss fights right around the corner. Join me at 9 ET for some Megaten adventures!

Part 9-2 of our SMT: Digital Devil Saga livestream is now on YouTube. We complete the remaining side quests before heading to Nirvana. We're climbing the tower in search of Sera and answers. Please share and subscribe!

Part 9 - 1 of our SMT: Digital Devil Saga livestream is now available on YouTube. We revisit the Vanguard Tribe's base to break the remaining color barriers and grab what we can. That takes us to an extra dungeon with Beelzebub as a boss fight.

[Перевод] Решаем задачу про ферзей при помощи SMT-солвера
Автор статьи Modern SAT solvers: fast, neat and underused утверждает, что SAT-солверы «преступно мало используются в нашей отрасли». [SAT — Boolean SAT isfiability Solver, то есть солвер, способный находить присвоения, делающие истинными сложные булевы выражения. Более подробно я писал о них ранее.] Какое-то время назад я задался вопросом, почему: как получилось, что они настолько мощны, но ими никто не пользуется? Многие специалисты заявили, что причина в неудобстве кодирования SAT: они лучше предпочтут работать с инструментами, которые выполняют компиляцию в SAT. Я вспомнил об этом, когда прочитал пост Райана Бергера о решении «задачи ферзей с LinkedIn» как задачи SAT. Вкратце опишу задачу про ферзей (Queens). У нас есть сетка NxN, разделённая на N областей, и нам нужно разместить N ферзей так, чтобы в каждом столбце, строке и области находился ровно один. Ферзи могут находиться на одной диагонали, но не соседствовать по диагонали.

Inbound SMTP DANE (DNS-Based Authentication of Named Entities) is a security protocol designed to secure email communication by ensuring the authenticity of the receiving mail server's encryption certificates when emails are delivered via the Simple Mail Transfer Protocol (SMTP).
By default, SMTP doesn't guarantee encryption, which makes it vulnerable to man-in-the-middle attacks. To secure email communication, SMTP can use STARTTLS, which upgrades a plain text connection to an encrypted one. However, STARTTLS by itself doesn't verify the authenticity of the receiving mail server's certificate, leaving it vulnerable to attacks where a malicious entity might impersonate the server.
DANE addresses this issue by enabling domain owners to publish their mail server’s encryption certificates in DNS records, which are protected by DNSSEC (Domain Name System Security Extensions). This allows sending mail servers to verify the authenticity of the receiving mail server's certificate before establishing an encrypted connection.
When an email is received, the receiving mail server uses DANE to publish its certificate in the DNS, allowing the sending server to check the certificate's validity before establishing a secure TLS connection. This ensures that emails are delivered over an encrypted connection and that the encryption certificate is trustworthy and has not been tampered with.

TIL that #Mittwald still doesn't support SMTPUTF8, an extension to the SMTP standard from 2008.
Folks, don't believe the marketing BS, choose another hoster, period.
