Since Brock has done me the favor of advertising TLB for me, I'll do a
quick explanation. Forgive me if I center too much on Majordomo; I've
never tried TLB on anything else.
Like bulk_mailer and splitlist, TLB lets you trade CPU and memory for
multiple parallel deliveries. TLB also lets you spread delivery out among
several hosts. I have five machines that deliver outgoing list mail in
parallel, and none of them is the machine that runs the list software.
While single-host parallel delivery is something you can get from one of
the newer MTAs, TLB can still be used to provide multiple host parallelism.
TLB is callable as a mailer from Majordomo, eliminating the need for (and
the security holes of) outgoing aliases. It can call archiving and
digestifying programs itself, so you don't need aliases to do those,
either.
TLB has piles of different sorting and batching options. TLB can send
addresses matching regular expressions to different sets of hosts, allowing
cheap domain-based remote exploding given cooperating remote machines.
The down side: TLB is big (written in perl, 5.003 and several modules
required), reasonably difficult to configure, and can consume huge amounts
of resources. I am not currently doing any development of TLB (though I'll
still support it and fix simple bugs) because I'm rewriting it and turning
it into a delivery engine for a future version of Majordomo. I may then
turn it back into a standalone product, but it will be a while before I
come to that point.
TLB is at ftp://ftp.hpc.uh.edu/pub/tlb/
