Apologies but I don't understand the question.

mlmpl is was a quick hack to run a smallish newsletter for fun and (no)
profit.  (it's still being used by the way.)

SMTP is quite resistant to offline/unreachable servers.  MX *should*
retry before giving up the delivery (I don't remember the exact number
thought) so this is a slightly minor problem in the mailing
list/newsletter world AFAIK.
