Testing SMTP and POP3 Connections

It often happens that I need to check a certain SMTP and POP3 connections. Whether it is the user credentials or the authentication methods. Using telnet is one method, but you have to make sure you don’t make typos while you are in the session. A much easier approach is to use a GUI tool named SMTP Explorer from http://outlook-net.de to test the SMTP connections. POP3 accounts can be checked using Magic Mail Monitor.
