When troubleshooting an IMAP service, it's frequently helpful to use the '''telnet''' client to "speak" to the server directly, rather than using a mail client which won't give you the exact responses the server does. In this example, we will use '''telnet''' to connect to an IMAP server, log in as a user, list the user's available mailboxes, and check messages in one of them.

ph34r# '''telnet localhost 143'''
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
* OK dovecot ready.
'''A LOGIN postmaster@mail.getsdeliveredhere.net thisismypassword'''
A OK logged in.
'''A LIST "" "*"'''
* LIST (\HasNoChildren) "." "INBOX"
* LIST (\HasChildren) "." "Sent"
* LIST (\HasNoChildren) "." "Sent.2006"
* LIST (\HasNoChildren) "." "Sent.2007"
a OK List completed.
'''A SELECT inbox'''
* FLAGS (\Answered \Flagged \Deleted \Seen \Draft)
* OK [PERMANENTFLAGS (\Answered \Flagged \Deleted \Seen \Draft \*)] Flags permitted.
* 1 EXISTS
* 1 RECENT
* OK [UIDVALIDITY 1103088195] UIDs valid
* OK [UIDNEXT 1] Predicted next UID
A OK [READ-WRITE] Select completed.
'''A LOGOUT'''
* BYE Logging out
A OK Logout completed.
Connection closed by foreign host.

Okay - we've just verified on a very direct level that the [[IMAP]] server we connected to answers incoming connections, successfully authenticates users, ''and'' successfully opens their inboxes - see the '''* 1 EXISTS''' and '''* 1 RECENT''' lines? That tells us that there is a single email in the inbox folder, and it hasn't been read yet. (We got "inbox" from the results of our '''LIST "" "*"''' command, which asked for a complete list of folders on this account.)
