Problems with Inbound Email

Friends, after have some port issues (looks like m RV345P stopped responding to forwarded ports), I'm faced with the fact that email from OUTSIDE-THE-NETWORK sources are not making to accounts within my network and cPanel installation. Emails sent WITHIN my network ARE making it OK to other users. Additionally, I noticed that my email client (thunderbird) is no longer probing for email settings when an email account is setup in the client?

Any suggestions is appreciated.

Hey there! Is this server hosted on a private network and not a datacenter? If so, short of replacing the router, I'm not sure what else you could do about incoming messages other than to move them all to an external service. You can confirm if the problem is the pot by doing a test with this telnet command from an external machine:

telnet x.x.x.x 25
where "x.x.x.x" is your server's IP address. if that doesn't work, no system would be able to deliver email to your server.
