I have configured replies@example.com that is hosted using roundcube, to handle reply to topics by email. It used to be a different GSuite email id which was working smoothly. I followed all the steps in this post.
When I send a mail directly to replies@example.com, it gets logged under rejected mail as intended.
This means that POP3 polling is indeed happening.
But replies to notification emails does not get posted. I have a feeling this is because of the way slugged emails are being handled. I’m able to see the emails in the web-client, so I know the slugged emails are also getting delivered correctly. Yet they are not showing up in ‘Received’ emails in discourse. They do not get deleted either, even though I had enabled pop3_polling_delete_from_server and other mails were getting deleted after polling.
What am I missing?
My error logs are clean. All the posts here only mention configuring with some kind of 3rd-party email services. My notification mail id, used for outgoing mails is also hosted from roundcube and that works fine.
