Do you send personalized messages ?
[ One message per recipient ]
How do you submit messages to sendmail ?
[ e.g."sendmail -odd recipeunt" or via smtp ]
Do you use multiple queue directories ?
[ available since sendmail 8.10]
How fast is your internet link ?

Putting messages directly in the queue is more efficeint BUT
consider using special queue and special sendmail.cf to process the
messages as non root user [ Do not use main queue directory
owned by root - it creates security risks ]
To process your special queue(s) use (as non root):
sendmail -q -oQspecial-queue-path -C special-sendmail-cf-path
