We have an email server behind our corporate network using a POP3 setup. The POP and SMTP settings point to the IP address of the email server which are NAT'd from the external IP. I want to be able to check our email from outside the network....i.e., on the road. I know that I need to make some DNS entries into our local DNS server and externally as well...but how do you do this specifically? Thanks so much for your help!
