I split my outbound list mail between several hosts using my TLB package.
Each list is sorted and divided into chunks (just like bulk_mailer, but
with more sorting and splitting options) which are then spread out over the
outbound hosts (which is unlike bulk_mailer). It's available from
ftp.hpc.uh.edu:/pub/tlb, but requires some technical knowledge to install
properly. It has the pleasant side effect of eliminating the security
holes opened by all of those -archive -digestify and -outgoing aliases.
It still uses whatever mailer you have installed to do the actual delivery.
(qmail, smail, sendmail, zmail, whatever; all it needs is SMTP.)
