Steps to confirm IMAP credentials or to test connectivity and functionality of the IMAP protocol 

GroupWise no longer allows for clear text login for the IMAP protocol
This means the Telnet utility will not work


Openssl can be used to initiate a client connection and login to a the GroupWise IMAP protocol using the following steps.

Open a terminal on a Linux server and enter this command:

openssl s_client -connect yourserver.yourdomain.com:993 -crlf

Note, substitute your server's FQDN or IP address as appropriate.  If SSL is not enabled for the IMAP protocol on your GroupWise agent then you will need to change the port from 993 to 143

If the command is successful you will see information about your GW system and certificate information will be exchanged  You will then be at an IMAP prompt that looks like this:


Now you can issue standard IMAP commands    To test a user's credentials enter this command:

a1 login username userpassword

The a1 is simply a command tag and can be anything you choose  The username and password should be a GroupWise userID and that user's GroupWise password   If they are accepted you will see a return like this:

a1 OK LOGIN completed

This confirms the credentials.  Issuing Ctrl - c  will terminate the client connection and return you to the terminal prompt


Enhanced security on the GroupWise IMAP protocol prevents clear text telnet connections
