E-newsletter bounce settings test fail.

Hi

I have been using e-newsletter successfully for a while on one site and was just setting it up for use on another.

I have been unable to perform a successful test of the bounce settings in the new domain and, after looking at the first domain where it was working, have now discovered this sites bounce settings are failing too.

I get the following error message in a pop up;

Warning</b>: imap_open() [function.imap-open]: Couldn't open stream {mail.schoolinformer.com:110/pop3/notls}INBOX in <b>/home/schoolin/public_html/wp-content/plugins/e-newsletter/e-newsletter.php</b> on line <b>1300</b>
Can not authenticate to POP3 server: Authentication failed.

I can confirm that the settings are correct but I have noticed that after saving, the password field is repopulated with a seemingly random string of characters.

I wonder if this is the issue. Perhaps the plugin is changing the password somehow?

It was tested and working fine on the first domain so I am not sure if this is since a recent update.

Thanks in advance

Stef
