Troubleshooting SmarterMail incoming SMTP requests

May 12, 2010 By Larry Brouwer Leave a Comment

Today, I discovered that SmarterMail isn’t receiving emails from other hosts outside my local network. I first logged on to SmarterMail as admin. Nothing apparently wrong with the mail system. I next opened up a Command Prompt and tried to telnet to mail.larrybrouwer.com 25 and it worked fine. Next, I logged on to a remote server and again attempted to telnet to the smtp service. This time, nothing happened.

My thoughts then turned to firewall issues. So I checked to make sure that the firewall wasn’t blocking port 25. It isn’t, but just to make sure, I disabled the firewall and again tried to telnet into the email server on port 25. I’m still not able to log in.

I next suspected my D-Link DIR-655 router as the problem. I logged into the router and checked the Virtual Server settings. The the router settings look fine. I then remapped port 25 to port 80 just to see if I can get through to the web server. Re-mapping didn’t work. Now I’m really puzzled.
