Joomla SMTP Configuration Issue CBMailing Error

I'm having an issue with the SMTP setup of my Joomla website when trying to send mass emails through the CB Mailing (Mass Email) extension. I receive this error:

SMTP Error! The following recipients failed:
Number of users to whom e-mail was sent: 0 (Total in list: 1)

I'm having an issue with the SMTP setup of my Joomla website when trying to send mass emails through the CB Mailing (Mass Email) extension. I receive this error:

SMTP Error! The following recipients failed: Number of users to whom e-mail was sent: 0 (Total in list: 1)

So, my question is: What is causing this SMTP error and how can I resolve it?

The mail log is stating that the email bounces back to the from email: ctaspa-info@ctaspa.org

The only user on the mailing list is user3@earth2525.com (I just ran a test to make sure that the user3 account works and it does). This is the content that comes up in the body of the bounced back email:

SMTP Error! The following recipients failed: when sending withTo: , <br />
(NULL), <br />
user3@earth2525.com,

Result=true<br />
<br />


The old version of this websites mass emailer worked fine, however, in order to add Kunena Forum and maintain compatibility I had to make several upgrades to the site including the upgrade to Community Builder 1.7.1. Both the new version and old verson configurations are outlined below.

Server for Website: Mac OS X Server 10.4.11, Apache 1.3.4.1, PHP 5.2.3, MySQL 4.1.22

Server for SMTP: Eudora Internet Mail Server 3.3.9 (EIMS Server X)

New Configuration:

Joomla 1.5.25, Community Builder 1.7.1, CB Paid Subscriptions (CB Subs) 1.2.2, CBMailing 2.3.4, Kunena Forum 1.7.0, Legacy 1.0 plug-in disabled

Mail Settings (New Config):

• Mailer: SMTP Server
• Mail from: ctaspa-info@ctaspa.org
• From Name: CASPA
• Sendmail Path: <span>/</span>usr<span>/</span>sbin/sendmail
• SMTP Authentication: Yes
• SMTP Security: None
• SMTP Port: 25
• SMTP Username: ctaspa-info@ctaspa.org
• SMTP Password: *******
• SMTP Host: 209.48.40.194

Old Configuration (Working SMTP Configuration):

Joomla 1.5.9, Community Builder 1.2, CB Paid Subscriptions (CB Subs) 1.0.3, CB Mailing 2.1,
Legacy 1.0 plug-in enabled

Mail Settings (Old Config):

• Mailer: SMTP Server
• Mail from: ctaspa-info@ctaspa.org
• From Name: CASPA
• Sendmail Path: <span>/</span>usr<span>/</span>sbin/sendmail
• SMTP Authentication: Yes
• SMTP Username: ctaspa-info@ctaspa.org
• SMTP Password: *******
• SMTP Host: 209.48.40.194

(Notice how the older version of Joomla is missing the 2 fields: SMTP Security and SMTP Port)

Thanks in advance!

The answer was right under my nose. The problem was that when I upgraded CBMailing the original configuration was reset to default. Most Joomla extensions maintain the existing configuration after an upgrade so I didn't think to even look there at first. So I set it back to the old config and problem solved.

If anyone is interested here is a working CBMailing Config:

• Allow attachments? checked
• Allow HTML? checked
• Method: One e-mail for the whole list
• Send from: A specific address, ctaspa-info@ctaspa.org
• Reply to: The person logged in
• Send to: The list addresses
• BCC recipients: No one
