Although we do receive password retrieval email, my students and I are not receiving notifications of forum posts, or mail sent through the system's messaging system via "Participants" >> "Send message."
I have
(1) left the SMTP settings empty, so Moodle would use PHP mail,
(2) entered credentials for a known-good school SMTP server, and
(3) entered credentials for gmail SMTP.
None of these works, and neither the system Log nor the PHP error log show signs of trouble - even though I
(4) set "Debugging" to DEVELOPER, and
(5) enabled verbose SMTP debugging.
Because I am using Moodle 2.6.4, which has some issues with /lib/phpmailer, I have also tried all of the above using the /phpmailer from 2.4.7, but with the same empty results.
I am hoping someone can either point out what I'm missing, or provide further trouble-shooting steps.
Thank you, thank you!
