Thanks a lot - a first hand account really helps.

In general searches on comparison between the two, most often claim
postfix to have better performance than exim (some qualify the statement
saying "for large queues" - which does not bother me for my use case, but
in your case you have seen it scaling well as well).

There are many of good examples and howtos out there which provide single config files you could easily adapt and use. But you can split config files too if you prefer that.

By profession I am a in programming languages researchers and have created
many DSLs in my career. I can say in light of whatever little experience
of inventing notations I have, postfix notation does not really sound
intuitive, particularly when the problem domain does not require it to be
that complex. I'll definitely give exim a try on this aspect.
