Hi --
I used Postfix along time but my experience is that it is incredible
difficult to implement custom logic especially across the different
binaries/processes it uses to fulfil a mail delivery transaction. Its
designed in the "unix philosophy" and has good performance - great but
Postfix devs normally react hostile if asked for advanced features that
require tracking meta-information about messages across Postfix
processes. Its only the RFC compliant mail message state that persisting
through the entire transaction, nothing more. Milters can be injected
but have limitations and I get headaches from the configuration system.
I shouldn't complain too hard tho, because I'm grateful for how solid
and secure and bulletproof it has been. Thank you team Postfix.
But I want more power and customization not only generic mailserver.
I heard of Haraka a time ago and I see it is still maintained, but there
seems no public archive of mailing list (website for years now has said
"We are working on providing list archives") and when I last tried to
subscribe, list was broken!!! I asked on irc and they said approx "oh
it's broken? meh, thats not so important, cuz Haraka just works, if it
doesn't just ask on irc. we update Haraka once in a while when we find
something wrong". Obviously this was a red flag.
Anyone using Haraka? Anyone trust Haraka?
That mean Exim is the only real choice? It was a good laughing from this
recent mailop post about Exim vulnerability and I see Exim gets regular
vulnerabilities.

But it look like Exim have infinite customization possibility which
should help me. I guessing that one must accept more vulnerabilities for
having more power flexibility that Exim gives.
Can I ask what are mailop's opinions about Exim? Thanks you!
