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, <br />
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. 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: /usr/sbin/sendmail
  • SMTP Authentication: Yes
  • SMTP Security: None
  • SMTP Port: 25
  • SMTP Username: ctaspa-info@ctaspa.org
  • SMTP Password: xxxxxxx
  • 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: /usr/sbin/sendmail
  • SMTP Authentication: Yes
  • SMTP Username: ctaspa-info@ctaspa.org
  • SMTP Password: xxxxxxx
  • SMTP Host: 209.48.40.194

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

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
