Postfix.
But that’s only an MTA i hear you cry, Exchange does both MTA & MDA! Bear with me.
Postfix is software to learn from. It might be written in C but the architecture is the epitome of beautiful modular design. It’s not just the meticulous separation of concerns, the care and attention to detail, everything from string handling to memory management is pristinely handled. https://github.com/vdukhovni/postfix
Even at runtime the beauty of the architecture allows for a sysadmin to choose (via master.cf) exactly how the components should be composed to fit their needs. The defaults are crafted for minimum fuss if you just need to get it running ASAP. The software is ergonomic in addition to being artfully crafted.
So what does all this care and attention get you? Only 9 CVEs in 22 years, only 3 of which are code exec, only 2 of which are (maybe) remote code exec, only 1 of which is unauth user RCE - but very hard in practice to exploit.
Maybe it’s just not that popular? It was 1/3 of all SMTP servers on the internet according to a 2019 scan.
So it’s the best MTA ever to exist, but what about MDA? Well, that was the whole point. Compose well crafted components together to build a system. You especially don’t run part of your mailserver’s web interface in kernel space because, well i’m not sure why IIS/Exchange does that :-)
