550 Error

[OzarkMartin]

I saw some posts on this and have contacted my server to assure I can use bulk email, but I cannot seem to debug this problem. It keeps asking for an authorization, here is the error:

Try to set MaxBulk Mailer authentication to ESMTP. That should fix your problem.

Thanks for the posting, however, it is still not authorizing. Any other suggestions? I have rechecked all email and passwords for correct spelling, etc.

Ok- I changed it to ESMTP Plain and it sent just fine- thank you of your assistance.
