Just so you know, this is NOT for any kind of a spamming site. I'm just curious if anyone has some estimations as to about how many emails I can reasonably expect one machine running FreeBSD 4.4-SECURE (or whatever that branch is being called now) with Sendmail to be able to send in a day. The machine(s) I'm looking at will be P3-933Mhz with 1GB of RAM. My main question is whether I will need to throw more than one machine at this. I've done some calculations, and 500,000 emails at 5k each is 2.5GB/day. Dividing that by 86400 (# of seconds/day) I get 28935 bytes/second, but I am promised by the client that I'll have the bandwidth I need, so I'm just mostly wondering if the machine will be the limiting factor, or will bandwidth be the issue? I'm asking in -isp because this is where I assume the heaviest use of mailservers would be in an ISP or similar situation. If this isn't the right forum, I can ask it in -questions but I thought the people in -isp would have more similar experience to what I'm asking. Anyone with any numbers they would be willing to share with me would be greatly appreciated. Thanks.
