Did what you suggested. Nothing informative was provided other than the email failed. the log in phpList provided the following: Error sending email to info@spycpowerboat.us SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting
The log file from my SMTP server provided the following: [I-075] Aug 14 16:26:42 [172.16.40.40:38800]SMTP Server: AUTH failed, username bounces#spycpowerboat.us, password 791b285d8462e1241601271b172098d0
The password should be the real password, but it appears to be hex. My server only uses plaintext authentication. I have to get phpList to use that. I cannot find where that setting would be.
