MailIntegration - Testing the POP3 connection


To test the POP3 connection used by MailIntegration:

  • Send an e-mail to the mailbox being tested
  • Use a program to test connectivity (Telnet, PuTTY, OpenSSL) by connecting to the appropriate server and port.
    • To test a secured connection, you will have to use OpenSSL.
  • Type the following command: USER UserName
  • Type the following command : PASS UserPassword
  • Type the following command: LIST
    • The server will provide the list of the message IDs in the mailbox. There should be at least one message.​
  • Type the following command : QUIT

If you aren't able to successfully complete this test, you need to contact your e-mail server or network administrator to help resolve the problem. Common problems are:

  • The server doesn't accept POP3 connections
  • The wrong combination of server name, address or port was used
  • The name of the mailbox(user) isn't recognized
  • The password for the mailbox (user)is invalid
  • The SSL certificate doesn't match the server name used.

Until this test is completed successfully, there is no point in testing MailIntegration.
