Troubleshooting SMTP Issues with Telnet
by Željko Filipin
I have really bad memory. I have to write this down. I just know I will forget it, but need it later.
I had to find out why one user did not receive any mail from us. I tried the usual things, but all looked fine. My colleague suggested to troubleshoot it with telnet. I found good article about troubleshooting SMTP issues. What I did:
- open command prompt
- find server
- connect to that machine with telnet
- not so good
