Hello Experts,

I testing out a third party email server called mdaemon.  Some of this stuff is foreign to me so I'm turning to you.

This is just a test environment.

What steps should I take to configure a Linksys WRT300N to allow an email server in the network?  
Should I be open certain ports, and or direct a protocol to the ip address of the server?

Just looking for some guidance as a place to start.

    A good place to start allowing external connections to your networks mail server would be PortForward:

    This will take you through forwarding the appropriate ports for your exact router model.

    Section1: nuts n' bolts
    1. Setup the email server cpu with a static LAN ip address. (ex:
    3. Forward port 110 to (the lan ip address of the mail server) (pop3)
    4. Forward port 25 to (the lan ip address of the mail server) (SMTP) ****
        - note that many ISPs now block port 25. If this is the case for your ISP, you will
          need to configure mdaemon to use an alternate smtp port, say 26 or something
          then forward that port to (the lan ip address of the mail server)
    5. Setup your mail clients incoming and outgoing mailservers to your WAN ip that you currently have.
    6. Done.
    Section2: going pro with it
    1. All the above and....
    2. Register your domain name.
    3. Upgrade your current high speed internet account to include a static IP address.
    4. Configure the router to use the static IP address
    5. look for a DNS service ( to manage the domain name & sign up for service
    6. Setup your domain name with the DNS service. Point the subdomain to your static IP address you configured in step 4.
    7. Setup your mail clients to use as the incoming and outgoing servers.
    8. Enjoy the admiration of your peers!
    Good Luck!

    oh yeah...if you have to use a special SMTP port, all the email clients will need to be configured to use that special port. (in the example, I used port 26)
