Nope, I've tried setting it to 200 messages as well but with no difference.

That's what I thought, but after the first run through there are about
1000 messages stuck in the queue (because they couldn't contact the
server.) Every time I start a queue runner another 20 messages go but
the rest are stuck, so I assume pre-queueing all the messages wouldn't
make any difference?

Are "figuring out where the mail has to go" and "sending it out"
actually two different steps? Because like I say the mail is being
queued, and flushing the queue still only sends one message per SMTP
connection - but if it's not "figuring out where the mail has to go"
until the last minute perhaps this could still explain why it's only
sending one message per connection.

Thanks for your reply!
