Telnet commands can be used to test IMAP4 connections to the mail server to a) see if we can successfully open an IMAP session on the server and b) if we can access a valid email address.

Below you'll find the standard syntax used for the telnet commands:

1. Use the telnet command to open a connection to the mail server, e.g. type: telnet 10.0.0.9 143 <Enter>

Note: if using Windows 2000, you may want to use the following set of commands to turn the local echo function on and display what you're typing. Local echo is enabled on Windows 2003 and XP by default.

• From the DOS prompt, type telnet <Enter>
• Type set local_echo <Enter>
• Type open 10.0.0.9 143 <Enter>

2. Important notes:  Telnet does not allow backspaces, so if you make a mistake when entering the commands, start over.  Each IMAP command line normally begins with a sequential number followed by a space, but you can use ? instead of numbers.

3. When the telnet screen opens, you should see the mail server's banner, similar to: 
* OK machine.yourdomain.com ModusMail IMAP4S 4.2.420.0 ready
(If you do not get a banner, check the IP address and firewall configuration and start the test again)

4. Login using the command '? login <username> <password>':

• If the mailbox is located in a domain that has its own unique IP, enter only the username, e.g. ? login betsy test
• If the mailbox is located in a virtual domain (that does not have its own IP), enter the full email address as the username, e.g. ? login betsy@abc.com test

5. The list command can be used to list all available folders. You could specify the name of the directory where mail is stored or enter the following: ? list "" "*"

6. Use the select command to display the contents of a specific folder, e.g. enter ? select inbox

7. Use the fetch command to display specific message information. Enter the message number followed by one of the following tags:

Flags - displays all message flags such as answered, flagged, deleted, seen or draft

Examples:

To fetch the flags on message #1, enter: ? fetch 1 flags

To fetch the flags on all messages in the Inbox, enter: ? fetch 1:* flags

Full - displays the full header information, enter: ? fetch 1 full

Body[text] - displays the message body (content), enter: ? fetch 1 body[text]

8. Logout using the 'logout' command, enter: ? logout

This is what it looks like on-screen:

* OK vop-tech-mm.vircom.com ModusMail IMAP4S 4.2.420.0 ready
? login betsy@abc.com test
? OK LOGIN completed
? list "" "*"

* OK [UIDNEXT 10] Predicted next UID
* OK [UIDVALIDITY 25627141] UIDs are valid
