of, course, but can CFMAIL deliver to an LSMTP's ip.ad.re.ss without doing
DNS lookup? That would be several 10's of ms to shave off CFMAIL execution.
hmm, I bet that' one expensive piece of software, LSMTP.
And I bet postfix with FreeBSD's softupdates filesystem and desintation
sorting could come damn close to LSMTP, and do it for free, with as many
SMTP clients as your memory could hold, and it that wasn't enough, do it
all again on a 2nd, 3rd, etc, PC, giving you n-way MTA delivery redundancy,
which is absolutely necessary with that many mail msgs to get out.
The email business is as fascinating as DNS workings.
