I'm trying to use Joomla's Mass Mail function to test emails being sent from Joomla and a contact form plugin (Fox Contact). When trying to send an email using the Mass Mail form, Joomla shows the error The following from address failed: [email protected]
([email protected] is the SMTP username and from address).
I have confirmed the SMTP details are correct in Site > Global Configuration > Server Configuration > Mail Settings I have also tested the configuration using a telnet connection from the web server, which is able to send emails after authenticating using the username and password in Joomla.
I then tried to enable SMTP debugging by editing ~/libraries/phpmailer/phpmailer.php
and changing $SMTPDebug
from false
to 2. However this does not show any additional output (other than the above address failed
message).
How can I fix the SMTP sending, or enable debugging to find the cause of the issue?
