Hello, i am using Moodle Moodle 4.2 (Build: 20230424) and PHP 8.1.9 versions on a Linux system, the installation is dockerized in a VM.

I've got a problem when a user click the forgot password or when someone subscribes for first time, the confirmation email failed to send.

These are my configurations on the SMTP, i remove the mail due to  personal info but its correctly filled, the mail that is filled is a Gmail personal mail. and i get this error on testing: conf

Qualifications for this response: none - don't host on Amazon, but I can google! smile

Error says:

Username and Password not accepted.
SMTP connect() failed.
https://support.google.com/mail/?p=BadCredentials

Suggestions:

The noreply address should be a user right on your moodle server itself.
noreply@moocs-academy.slices-ri.eu

(above sendmail aliases)

Your moodle server IP address should be included in SPF records for your top level domain.  Would be best if one had all other: like DMARC and DKIM.
https://docs.moodle.org/404/en/Mail_configuration


Consider installing something like a Postfix localhost/send only MTA.
You'll have a mail server instance on your moodle server then and it keeps logs
that you could inspect to help troubleshoot this.

Also consider using Amazon recommendations/docs
https://docs.aws.amazon.com/ses/latest/dg/eb-relay.html
https://docs.aws.amazon.com/ses/latest/dg/send-email.html

Good luck!
