An anonymous reader writes: My boss has recently asked me to find out about creating a distributed email distribution system to distribute marketing materials globally. We intend to send about 300 million emails every day. Obviously, we're going to need a lot of bandwidth. But my worry is that our IP addresses are going to get black listed by SPAMHaus and the like very quickly.
The current proposal includes using a dozen servers powered by AMD processors, with one of them acting as an "email pool" from which the others request a new batch of addresses. They will all be running Debian GNU/Linux. The tricky part is the networking — ideally we'd want to use something like Tor. As it stands, the plan is to use multiple T3's, but again, we're worried about our static IPs getting black listed.
Have any of you set up a distributed email distribution system before? How much hardware did you throw at the problem? How did you circumvent blacklisting? Any suggestions would be greatly appreciated!
