My personal email domain is being hosted by Zoho.com.? I set up the DKIM records as they show.? For over a year it has been working just fine.? Around the end of May all emails from groups.io started bouncing.? I can send to my groups, but I do not get the message in my inbox.? All message from any group and from anyone bounce now.
I checked the DKIM records, and they are OK.? It appears to only be messages from groups.io.? I am getting email from everyone else OK.
Where can I look to try and figure out why?? I don't see anything helpful in the logs.? This is the only message I see and it is on every message.? "554 5.2.3 MailPolicy violation Error delivering to mailboxes".
I talked to Zoho, and they recommended setting my DKIM to "quarantine" instead of "temporary reject".? I just did that.? I also white listed groups.io.? I sent a test message and it didn't bounce this time.
I am not a fan of white listing!? Any suggestions or help on where to look wold be appreciated.
