What IT Geek 31 was asking for originally was "TLS and SASL support", perhaps 
from pkgsrc, when others noted how to configure base system Postfix to provide 
at least TLS.

Alistair C. then started thinking about a "small mini_sendmail STYLE MTA"...

I find it entirely reasonable that someone would want to build a tweaked MTA 
from pkgsrc or whatever.  I also find it reasonably common for people to stick 
with the base MTA, without doing anything more than adjusting configs.

Well, I'm OK with the *notion* of a minimal base MTA, but I recall looking 
around at various alternatives and not finding anything I regarded as a 
reasonable alternative.

(If the prospective MTA can't resend after getting a 4xx temp failure from the 
mail hub, or it can't manage to do SMTP protocol on localhost:25 for local 
processes trying to send email, then it's not usable...not for my purposes, 
anyway. :)
