I get the following when trying to send confirmation e-mail from event registration

The mail library returned the following error message:
 authentication failure [SMTP: Invalid response code received from SMTP (outbound mail) server while attempting to send email. This is often caused by a misconfiguration in the CiviCRM Outbound Email settings. Please verify the settings at Administer CiviCRM >> Global Settings >> Outbound Email (SMTP). (code: 535, response: 5.7.0 ...authentication rejected (6))]

This is probably related to a problem in your Outbound Email Settings (Administer CiviCRM » Global Settings » Outbound Email), OR the FROM email address specifically configured for your contribution page or event. Possible causes are:
•Your SMTP Username or Password are incorrect.
•Your SMTP Server (machine) name is incorrect.
•You need to use a Port other than the default port 25 in your environment.
•Your SMTP server is just not responding right now (it is down for some reason).
•The FROM Email Address configured for this feature may not be a valid sender based on your email service provider rules.

But, the Save and Test e-mail in Global Configuration/OutBound E-mail works perfectly (and the SMTP server is not down)
The Global Configuration/From Email screen has that same e-mail as Outbound
The Configure Event/Online Registration tab has that same e-mail (in name@comcast.net format)

Does the Online Registration tab need an index into the From Emails instead of a standard-form address?  How can I debug this.

Thanks

I set the front end CIVICRM_SITE_KEY (components/com_civicrm/civicrm.settings.php) to be the same as the back end (administrator/components/com_civicrm/civicrm.settings.php) and it worked - although it returned a message saying profile and account was "not saved"

emails were sent though and both user and ciccrm contact were created and the contact  and the user could log on.

Those are files in a Joomla site. 

Surely, there are comparable files in a Drupal site, but I could not name them.

I cannot give you any specific advice on Drupal config, but I am going to guess that you installed Drupal at bluehost, and copied files to Bluehost.

The installation of Drupal probably generated an encryption key (for things like passwords), that would fail to decrypt any encrtypted data that you copied over.  So you might want to double check that you set the encryption key back to what it was at your old site.
