Hi Wanan,

Your MX record should have your mail server's statis IP address. For you that appears to be 202.158.44.44.

I used an "A" style MX with static IP number of 68.15.242.97. I used the name "mail.smvfp.com" in my MX records, which resolves to my static IP address of 68.15.242.97. I have an account on my SMTP Server, local address of 192.168.1.109, with user name lelandj, so you can send me an email using my mail address of: lelandj@mail.smvfp.com. My router's WAN address is 68.15.242.97 which make it a node in my ISP network connected to the internet. I forward all packets coming in over WAN address 68.15.242.97, ports 110 and 25, to my local 192.168.1.109 mail server.

Once mail hits your 202.158.44.44 WAN router, then you could forward port 25 for SMPT and port 110 for POP3 to your local SMPT server.

Users in the local network could setup multiple email client accounts to access their IMAP and POP3 email. You could also have your SMTP server forward mail to another computer inside or outside your local network, and then have your user access their mail there.


Hope this help.

Regards,
