John,
Your server should be able to handle that many messages in under 5 minutes.
Some mail servers do reverse DNS lookups and other verification to verify
your mail servers identity. Make sure you have everything in your DSN for
that mail server just as if it were a mail server receiving mail.
Make sure your domain has an MX record, make sure yourdomain.com has an A
record, and the ip address on your server has a reverse dns entry. When my
reverse dns entries were not set up correctly, I had trouble sending e-mail
to AOL.
