Hello, I am using OJS 184.108.40.206 and I managed to configure email functionality correctly because system can send password reset emails, new issue published notifications, and submission notifications But the system throws the following error (There was a problem sending an email message. Please try again later, or contact your system administrator.) when I am using email functionality in the workflow like sending email to reviewers or authors or editors. Please help.
As you’ve determined, that means that the basic SMTP configuration in your
config.inc.php file is correct, as some email is delivered. However, your SMTP server is rejecting some messages, probably based on content or addressing. If you have access to your SMTP server’s logs, they will tell you exactly why the message was rejected. I suspect it’s due to DMARC configuration, e.g. the “From” address in the messages does not pass DMARC tests and thus your server is rejecting it. There are some posts about DMARC in the forums here that might help.
