Multiple Mail servers for one domain. Using cPanel? or Manually?
I'm setting up 2 servers now for a project.
Another, older server will be handling WWW and would contain couple websites + webmail
Another one Mail(MTA), Nameserver, MySQL
Now, first i was thinking that i could get cPanel license for both servers, going to need an external so 40-60e/month per server.
But the problem is, i need to have capability for 100k e-mail users with anti-spam (SpamAssassin).
Mail server: Dual 2.8Ghz Xeon with 1Gb ECC Ram, with both massive IDE Raid (total 800gb) and smaller SCSI raid for system files.
It can't sustain that amount of mail users with anti-spam, can it?
Assume 30 e-mails per user per day, sounds quite low to me, that would come to 3million e-mails per day.
So, if i go for cPanel and it's automacy wonderland, how can i expand easiest way the resources, is there any easy way to add an another e-mail server to this setup, preferrably without another cPanel license?
With easy i mean that without much past MTA configuring experience (just some basic stuff with other MTA) it wouldn't take more than like 3hours to configure the MTA on both boxes to allow this kind of system?
How would you do this?
I'm in a hurry to make a decision.
If i go manual all the way, the configuration time is just sooo long needed for everything, cPanel would save from so so many hours of work and ease the future upkeep of the servers so i would prefer it.
But in a system like this, should i go for doing everything manually rather and spend the whopping 100h++ to configure everything upto top notch?
The thing is that the nameserver will be for whole datacenter and it's whole client base, so there will be some additions and changes each month. I expect about 10-30 new zones each month, and 30-50 other smaller nameserver changes for each month.
With cPanel we could delegate this to clients.
We could cripple the Apache on cPanel so we can give everyone reseller accounts (NS config & custom theme) and they could create themselves their zones etc. plus mysql databases they need.
Thanks a lot of answers! I'm really awaiting to hear opinions, ideas etc. about this one
