I wanna run web server, mail server and MS SQL Server on the same dedicated server (AMD Opteron 170 with with 2 GB DDR 400 RAM).
We plan to host in this project only 5 websites (3 of them with forums and 10-70 users online and heavy content DB driven/ another 2 small ones) and about 120 e-mail accounts (virus scannning and spam block outside the server).
With your experience, what´s the possibility of run this server smoothly and offer a good service?
What´s the risks? pros? cons?
It´s temporary situation. When I got 120+ e-mails accounts, I can migrate the mail server system to a proper dedicated server.
I would think you would see few problems with the RAM you've got unless you're running a really heavy hitter. Frankly 120+ emails is nothing for that machine. I've seen hard hit mailservers (Linux) with several thousand accounts run fine with less.
