Question / Problem
We are using smart pop3 exchange, we are not receiving any external emails, ive looked in the logs and there is the following error message " Error while opening smtp connection "our server name " authentication unsuccessful " Also when I look on the server error log under applications there is the following error message "smartpop2smtp application error message "error while opening SMTP connection to "OUR SERVER " already connected.
Answer / Solution
The error "authentication unsuccessful" may occur because of the following reasons:- you entered a wrong username or password (also check if your pop3 server requires SSL). Try connecting using a standard mail client like Outlook Express or try it using telnet:
