RE: Can this be done? Email/Firewall Question



Title: Message
If you have a local DNS server which is inside your firewall then you don't have to open the firewall port...just send the DNS requests to the local DNS server.
 
If you don't allow remote collection of email (collection by people outside your firewall) then you don't have to open port 110 either.
 
If you need a hand with qMail drop me a line.

Thank you so much.  One thing, what do I need to do with DNS,  right now I do not have that port open.  Windows 2000 is my DSN server and is running great.  Does DNS have to run on the Red Hat server or can I keep it on my Windows box?  I will also be going with qMail.
Thanks again Kevin

the answer is yes and yes.
 
This can be done inside and outside the firewall...it is best to do it inside the firewall.
 
You will need to consult your firewall documentation to open the necessary ports, namely 53 (DNS), 25 (SMTP) and 110 (POP3).
 
I recommend qMail as a sendmail replacement.

I want to setup email for my domain, user mydomain com .  I have one Internet IP and everything is NATed to my 4 servers.  I'm running Checkpoint Firewall 1 software on a Nokia box.  Does the email box need to be outside of the Firewall?
