e-newsletter: SMTP cannot connect to smtp host

I am trying to get the e-newsletter plug in running on my wordpress mu at aorealestate.com. I have installed the wp stmp plug in and then added the recommended code to my config.php file for multi user sites.
When I go to the settings dashboard of the e-newsletter plug, I can not get it to connect to the stmp host and I can not get the POP3 to work.
One weird thing is that even though I input the password for my email account in the password place and save it, it will reflect the change only until the page is refreshed and then it reverts to this smaller password (not sure what it is but mine has 19 characters)
