a lot of it you can browse, I don't know enough about OX to say whether or not it's buildable - but seems to be a frontend to things like postfix, etc.?

Principalmente porque se preocupam muito mais em falar de código do que sequer explicar os conceitos que eles adotam. Postfix por exemplo é mil vezes mais fácil depois que você entende os termos e o fluxo interno dentro dos processos dele

#sni und #ISPConfig für #postfix und #dovecot - bisher sind entsprechende Funktionen noch nicht integriert. Im Forum habe ich dazu ein #Shell-Script gefunden, welches ich mal ausprobieren will.
Ich habe es mal in ein #git-Repo gelegt.

Postfix has supported ECDSA certificates for over 16 years ago. EXIM and Sendmail have (technically) supported them for 20 years. MS Exchange only started supporting ECDSA certificates very recently, but all the versions that do not support them are now EOL.

At the moment, I’m using exclusively ECDSA certificates for my SMTP servers. Is it really worth the trouble of running “dual-stack” RSA/ECDSA certificates? It would be a right pain managing the lifecycles along with key rollover for DANE TLS.

@tante mailcow as an example is pretty great, here containerization just serves to help curb the horrifying complexity of managing an email server. i just switched to it from a manually-managed postfix + dovecot setup that exploded for reasons i genuinely could not discern with a fedora update […]

Stop 'reactions' to email by adding a postfix header (2024)
Attempting to stop Microsoft users sending 'reactions' to email from me by adding a postfix header
Over the past few months, I’ve noticed that an increasing number of replies to email that I’ve sent are “reactions”.

✨ Explore this trending post from Hacker News 📖 📂 Category: 💡 Key idea: Over the past few months, I’ve noticed that an increasing number of replies to email that I’ve sent are “reactions”. I imagine that, to the sender, or to someone in the Microsoft ecosystem, they are handled a bit liked a “thumbs-up” or “heart” reaction to a Signal message.
