Joomla can't send test email or any email

Post by pambesteder » Fri Aug 12, 2022 3:06 am

I'm on Joomla 3.10.10

I cannot send a test email using PHP, Sendmail, or SMTP. I get an error message whenever I try:

PHP:
  • Could not instantiate mail function
    Test mail could not be sent.
Sendmail:
  • Could not execute: /usr/sbin/sendmail
    Test mail could not be sent.
SMTP
  • SMTP Error: data not accepted.SMTP server error: DATA END command failed Detail: Missing internal data in the header. Message discarded. SMTP code: 550
    Test mail could not be sent.
I created a form and enabled user registration to see if I would at least get those:
  • I was able to complete the form
    However, the email didn't get sent
    The user was created in the backend but without access
WHAT is going on and HOW do I fix it?

Thanks
Pam

The SMTP error code 550 is a non-delivery report (NDR), in other words, a bounce. The receiving SMTP server has rejected the email and returns it.

The following tutorial shows how to use the Gmail server to forward email messages: How do I use Gmail as my mail server?. Try Gmail just to see that the PHPMailer in Joomla 3.10 works all right.

Please note that SMTP errors and lost emails can be caused by issues in SSL certificates or inconsistent mail domains, different from the domain of the web server, and also restrictions set by the web host network.

Enable the Debug option in Global Configuration and configure the plugin System - Debug to write everything to do with mail into a log file for the user group you are using for testing. Download the log file and post the relevant messages here for advice.

Thank you. It didn't matter which type I used to test if the mail was working. They all failed.
And the registration form failed as well.

Contact your host and find out what they recommend. Joomla 3.10 sends emails and the SMTP mail works, as long as it has been configured correctly and the host allows SMTP connections to external servers or their sendmail or SMTP server is used.
