If for any reason the POP3/IMAP4 connection fails to authenticate, you can test a connection for either POP3 or IMAP4 via TELNET:
POP3 TEST:
The first set of instructions establishes whether you have (and therefore Supportworks will have) access to an account on an Internet mail server:
- 1..On the Supportworks server, run a Windows command prompt.
- 2..Enter the following to verify that you have POP3 access:
TELNET <mail server> 110
You should now be presented with a banner informing you that you have connected to the mail server.
- 3..If the above is successful, enter the following in the case of POP3:
- USER <username>
- PASS <password>
- LIST
where <username> is the login ID for the relevant account on the mail server, and <password> is the required password.
If you can now see a list (POP3) or the number (IMAP4) of valid email messages within the account's Inbox (assuming such messages have been received), this proves that you have access to either a POP3 or IMAP4 service account. You should now disconnect from the mail server (QUIT or 3 LOGOUT, as appropriate) and close the command prompt window.
If unsuccessful, the mail/exchange administrator would need to be consulted to make the necessary changes to the Exchange server or provide alternative authentication details.
IMAP4 TEST:
- 1..On the Supportworks server, run a Windows command prompt.
- 2..Enter the following to verify that you have IMAP4 access:
TELNET <mail server> 143
You should now be presented with a banner informing you that you have connected to the mail server.
- 3..If the above is successful, enter the following:
- LOGIN <username> <password>
- SELECT INBOX
where <username> is the login ID for the relevant account on the mail server, and <password> is the required password.
If you can now see a list of valid email messages within the account's Inbox (assuming such messages have been received), this proves that you have access to either a IMAP4 service account. You should now disconnect from the mail server (QUIT or LOGOUT, as appropriate) and close the command prompt window.
If unsuccessful, the mail/exchange administrator would need to be consulted to make the necessary changes to the Exchange server or provide alternative authentication details.
