If I were doing this on a box I ran I would use php/perl to write the 
messages to file, then call the inject function of your mail server 
software (I typically use Qmail so its qmail-inject) which will take the 
message and deposit it in the queue. You can eliminate the overhead of 
the mail() function if you have direct access to the queue. Qmail runs 
20 simultaneous threads by default, so if you have reasonable DNS lookup 
speed you should be able to send at least 5 to 10 mails a second this 
way I'd think.
