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)

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: [email protected]
• From Name: CASPA
• Sendmail Path: /usr/sbin/sendmail
• SMTP Authentication: Yes
• SMTP Security: None
• SMTP Port: 25
• SMTP Username: [email protected]
• 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: [email protected]
• From Name: CASPA
• Sendmail Path: /usr/sbin/sendmail
• SMTP Authentication: Yes
• SMTP Username: [email protected]
• 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)

Thanks in advance!
