authentication or unknown error!

I get this message (on the connecting to server to que messages screen) all of a sudden when i try to send an email, listmail worked fine yesterday. Due to us having server problems i changed the www DNS record to point my domain to a different server, although the only thing that uses the domain name in listmail is the bounce back (i havent changed the MX records and my usual email still works), when i do a test settings i get this.

[Bounce Handling]
Is enabled?  Yes, Using a mailbox
Connecting.. Connected!
Verifying username and password... Verified!
The bounced message mailbox is configured correctly.

[SMTP Server]
Is enabled?  Yes
Connecting to SMTP server.. Connected!
Sending test email to remote address.. Problem setting receiver to Remote Test Address
The SMTP server is not configured correctly. Check your settings.

if i change the test email address i get a message saying everything is OK (and the test message to my inbox), but when i try to send mail, i still get the same error message.
Also I havent changed anything on my server except adding a domain as mentioned above.

This is likely due to an authentication error.  I recommend enabling the SMTP log during your mailing, or globally from the Config page (v1.87+) so we can see more information.

Be careful posting sensitive information to the forum, such as your base64-encoded username and password along with your SMTP hostname.

Strange, the MAIL FROM and RCPT TO lines not contain any email addresses.  There may be a problem reading the data from the ListMail database... or something else.

To learn more and/or find a possible bug I would be willing to do some hands-on testing for free on this.
