Hello @ctgraham @asmecher
Describe the issue or problem
Some email sent by OJS are rejected with the following return message:
Our system has detected that this message 550-5.7.1 does not meet IPv6
sending guidelines regarding PTR records and 550-5.7.1 authentication.
Please review 550-5.7.1 https://support.google.com/mail/?p=IPv6AuthError

Steps I took leading up to the issue
Automated Article Review Request email from OJS itself to a reviewer’s email adress.
What application are you using?
What and how can I configure the email sending in OJS to prevent those errors in future? Will this be solved after upgrading OJS to the newest version (which we will do shortly)?
A general guide to configuring email in OJS can be found here:
In short, you must use the
config.inc.php settings to specify a sender which is compatible with your (or your hosting provider’s) SFP and DMARC rules, including DKIM signatures.
What is your current email configuration in config.inc.php?
