This is an aspect I hadn't considered fully...I use bulk_mailer
for delivery to sort the recipient list by domain, allowing, say,
all messages destined for AOL or Netcom to be sent off in one
SMTP transaction. For my moderate sized lists it's a big win, and
I'd have to say it'd be a HUGE win for large lists where you're
likely to have multiple subscribers at each domain.
