Email Server Decisions
Currently a client of mine has a 2003 server which is their domain controller, file server, RRAS server and email server.
The problem at the moment is the email software is crippling the server and also the users PST files
What I want to do is move it to a dedicated mail server, move their PST files to the new servers storage (135GB) and that way takes the additional load off the server.
However this is only for 6-12 months until they can afford an exchange server.
The box will host 100 users, spec is single quad xeon, 2gb ram, 146GB raid 5
I have been looking at the CentOS 5.1 guides and cant decide which one to go with. they will need email filtering for both Email and AV, also currently users connect via pop3 both internally and externally, however the external users use auth smtp to send mail out and internal users are automatically authenticated.
so its between the following guides
Virtual Users And Domains With Postfix, MailScanner, Mailwatch & MySQL On CentOS 5.1
Mail Server Setup With Exim, MySQL, Cyrus-Imapd, Horde Webmail On Centos 5.1
Now it needs to be able to be administrated remotely both internally and externally via the web as I have to support this.
What would you recommend?
