    Hello!

    I recently switched out my wireless router. I had a Netgear 802.11g wireless router, but got rid of it for an airport extreme base station with built in print server. Since I switched to the basestation, I can no longer send out email with my ISP's SMTP outgoing mail setting (it is a cable company/cable modem). If I hook up the older Netgear, it lets me send mail fine. Right now I have a regular wired Belkin router that is connected between my cable modem and my apple basestation (turned off distribute ip addresses), and it lets me send mail fine... but I really want to get rid of the Belkin and the Netgear all together, and just use my apple basestation. Please help! Thanks!

    That would mean that the Airport Extreme/Cable Modem combo is blocking outgoing traffic on port 25. I don't have an Airport Extreme to look at the configuration, but I can't image they would configure it this way by default. Have you shutdown the cable modem for several minutes? I've heard some have flakey behaviour that a reset helps.

    Tried powering off/on Cable modem

    Yeah, I tried powering on/off Cable Modem but it didn't help. I am sure it is port mapping, but I am unsure how to do it exactly. Do I have to assign all my computers static ip's to do port mapping?

    I don't think any port mapping is needed. Can you try to telnet to port 25 of your ISP's SMTP server? You should see something like the following.

    Trying 207.115.57.25...
