Testing POP3 using Telnet

Posted by shauncroucher on August 11, 2009

I wrote an article on Experts Exchange recently detailing how to test a POP3 service using telnet.

Telnet is such a simple tool, and yet offers so much during troubleshooting. You can cut the problem right back to basics. If it doesn’t work with telnet, then you know that it is nothing to do with the configuration settings or complexity of the application you are using to POP collect. You can work from this principle up. Bit like the OSI model for networking….start at layer 1 and physical connections etc (ie – is it plugged in) and move up from there!
