AFAIK, this can only be a problem in your firewall/router configuration.
The routing/firewalling configuration for port 80 should have nothing to
do with the port 25 configuration for your net.
You should look with who configured your firewall/router to see how does
it work with SMTP/port 25 connections.
Hope it helps,
