cox email

I have used a Linksys router for a long time and suddenly I cannot send an email message to other than other Cox servers. I get a failed mail message that says, "Server response 550.5.5.5 joe@gmail.com, relaying not allowed." I can unplug the hard wire from the router and plug it directly into the modem and email works fine. The WiFi devices work (phone, printer, lap top). How come?

What server are you sending through that gives that message? Sounds like your trying to send through Cox SMTP server using a Gmail username? As for why it works plugged directly into the modem, I have no idea. What kind of router is it? Maybe it has a VPN or proxy built in.
