This should be a piece of cake question to answer for anybody that has spent
any time as an IT guru (which I haven't ;-)
I want to set up email hosting for my company. We currently have a hardware
firewall that provides DMZ, outside and local intranet connections guarded by
policies. We have a fat pipe coming into the firewall.
I want to place a bastion host (a hardened Linux box) on the DMZ running
postfix as the SMTP server and qpopper as the POP3/IMAP server.
I want all employees to be able to use the SMTP server to send out all mail
from the intranet. They should also be able to access their mail stored on
the bastion host via POP3 (IMAP?) from the local net to the bastion host
through the firewall. It would also be nice if they could access their mail
from outside the company via IMAP.
Perhaps later, another two bastion hosts on the DMZ running FTP and HTTP
Is this doable? Does this pose security risks?
Thanks for your comments.
