I have the same e-mail problem: Message I get is:Email Error: SMTP Error: The following recipients failed:
Then I phoned with my host: host gator and they told me everything seems to be set up right, but there might be a problem in the php script or the backend.
When searching for the SMTP error, I got the following:
/home/herb11/public_html/includes/classes/support/phpmailer.lang-en.php

Line #13 : $PHPMAILER_LANG["authenticate"] = 'SMTP Error: Could not authenticate.';

Line #15 : $PHPMAILER_LANG["recipients_failed"] = 'SMTP Error: The following recipients failed: ';

Line #16 : $PHPMAILER_LANG["data_not_accepted"] = 'SMTP Error: Data not accepted.';

Line #17 : $PHPMAILER_LANG["connect_host"] = 'SMTP Error: Could not connect to SMTP host.';

I am sorry, if the same questions where asked before, but I tried to find an answer and couldn't. I am also very new on this. Here is the website address: http://www.allnaturalherbaltherapy.com

Hope someone is able to help me
