Sending 80,000+ emails less than 6 hours
As title states, i need to send 80,000 emails within 6 hours. But without causing a huge load on the server while doing so. I don't want to go to a 3rd party emailer, although I would be interested in their delivery times for a mailing list of this size.

PHP, PHPMailer

Any suggestions?
