I had to send out 28000 messages last week (spamming the entire
university, don't ask). I just had a little script which did
sendmail -oi -odq address < messagefile
for every address (where "sendmail" is, of course, a link to exim :-).
Then I had about 3 concurrent "exim -q" queuerunner processes going
through the queue and I'd manually start up another whenever one got
through to the end. They went at about 10 per second and there weren't
any problems. With 7000 you should be fine. The only potential pitfall
is if they can't get shipped out quickly enough: mine were going
through to our mail hubs which took them off my hands pretty quickly.
