At my day job, we looked at PowerMTA for a product we built. Like
you, we were generating custom content for each message rather than
one message to many recipients.
We were invoking qmail-inject or the sendmail wrapper from within Perl
and found that the fork was costing us the most time by far. We
couldn't figure a way around this. We were submitting at a rate of
about 2 msg/sec which was just too slow.
We replaced that invocation with the Perl bindings for PowerMTA and in
our tests saw it ramp up and eventually settle at about 1000 msg/sec!
This was into a farm of SMTP syncs we set up rather than to real
servers on remote nets with dubious DNS issues.
Very impressive.
PS: If I'm just overlooking something about how to invoke qmail-inject
from Perl and not suffer a 0.5 second penalty for each, please let
me know.
