Outbound Mail Blocked
R8000 Nighthawk Firmware Version: V1.0.3.48_1.1.33 or 1.0.3.54_1.1.37 (went back a version to see if the latter broke anything) I receive emails all day long but cannot send email through the route...
So here's the short version: Port 25 is blocked by some ISPs as a matter of fact due to the amount of spam traffic that can be generated on that port. My ISP is one of them and only accepts outgoing email eminating from port 587. I enabled port triggering and port forwarding incase it was being blocked by the router for some unkown reason.
Tonight I found the solution though with the help of a very knowlegable tech support agent from my ISP. My ISP leases IP addresses on a month by month basis. The IP address is assigned by MAC address. The IP address that I was assigned this month was in fact Black Listed. (Don't Trust Tech Support, go find out for yourself) No matter how many times I reset the cable modem or the router the factory defaults, I would be assigned the same Black Listed IP address. Under the Advanced tab of the Netgear Genie, under Setup, under Internet, you can change the MAC address of the router. The Default MAC address and "Use This MAC Address" are the same until you select "Use Computer MAC Address". Then "Use This MAC Address" is filled in with the address of the device you're using to manage the router. Changing the MAC address, got me a new IP that wasn't Black Listed. The fact that I used an older router with a different MAC address got me a different IP address. But when I hooked the Nighthawk back up I got the same Blacklisted IP. Different MAC addy and now mail works fine in both directions.
I'm posting this solution as a courtesy because I spent a good 4 hours sifting through posts in this forum that were not pertinent or never had a solution.

If you're not running any servers, then why are you doing any port
forwarding or triggering? And what, exactly, _are_ you doing with your
"Port Triggering & Forwarding enabled on 587"? As usual, showing actual
commands to or reports from the device can be more helpful than vague
descriptions or interpretations.
I'm a port-25 kind of guy, so I know nothing about port 587 except
the a Web search suggests that it's associated with sending e-mail. My
first guess is that whatever you did with port 587 is what's stopping
your e-mail.

And did you fiddle around with forwarding of port 587 on that router,
too?
