SMTP Error with Formbuilder

[climberusa]

I'm using smtp in cmsmailer with formbuilder and the settings are correct as I've triple checked them and the email always shows up as it should. However, I'm running into this error:

SMTP Error: The following recipients failed

When I submit a form. The form always gets emailed and entered into the database but it says there is an error when there doens't seem to be. The forms in question have additional information for the user once the form is submitted but if they get this error they can't go any further.

I've tried using mail and sendmail but they were both unreliable. Maybe it's my hosts fault but the smtp settings are through the host as well (both dreamhost).

Has anyone else had this problem or know what I might be overlooking??

Appreciate the help!
