On around 29 September 2021, my Discourse forum log shows that no new incoming messages to the forum were being received. No messages were being bounced either - messages sent to the forum now simply never make it to the forum software - they disappear without any kind of response.
No settings changes have been made to the forum software, or in Digital Ocean control panel. The forum MX settings as shown in my Digital Ocean control Panel are still in place and correct.
Mailgun is the email provider for the forum, but again no settings there have been changed, and there are no errors logged by Mailgun.
MXlookup for the forum domain www.nzarchitecture.net.nz shows no errors, though there is one warning ‘DMARC Quarantine/Reject policy not enabled’ - but this is unchanged from when the forum was receiving emails normally.
Why is this suddenly happening? More importantly, how can I resume normal behaviour?

Hi @ArchPrime,
This is really weird. What I’ll suggest is trying to send an e-mail from an external provider to any mailbox you have access on - nzarchitecture.net.nz. That way, you can check your mail logs to see if the message was received, or if it didn’t reach at all, you’ll receive a bounce-back give you an error which then can be followed to the real issue.
Those are the first steps, I’ll recommend trying.
