I have a D-Link wifi router with the same problem.  Rather than try to kludge things to get around the problem I found it easier, and ultimately better, to run a split DNS.  So, when my wifi clients are on the internal network they are given the LAN IP address of the mail server when they use the FQDN.  When they are outside they get the external IP address they get the external IP address.
