Exim Server Sending From Different IPs

[Andrew Rosolino]

I am not sure what the best way to go about this is. We run almost 200 websites on one of our servers and each website has a quite large user base. Usually 10-20 of the websites will send out mass e-mails but the problem is Yahoo and other e-mail hosts don't like the volume being sent from the IP address so they defer the messages. This creates a huge backup of thousands of e-mails. I have about 10 unused IP addresses that I would like to randomly be chosen to send the mass e-mail from.

Is it possible to have the exim server randomly choose an IP address to send its mail from?
