Kevin - I believe they do send some bulk emails, that was one of our thoughts yesterday.
What was strange was that they were able to send to Google for about 4 hours yesterday afternoon and then it started happening again. There was brief respite where I thought I resolved the issue. All other domains work perfectly fine - no bounce backs, no error messages, nothing. I have also tested without the signatures and the messages are still being rejected. Sending blank messages or messages with just simple text strings still get rejected. I have another customer who uses Google Workspace, where I could potentially take out a ticket on their behalf to have Richmond.bbb.org struck from the spam list. Mark W.

This message was sent from outside your organization. Hi Mark, I saw this and your test from the loopback. Everything looked good from ARC/DKIM/SPF/DMARC. We've been seeing Google requiring DKIM authentication lately so we wanted to confirm that wasn't the issue. Are you sending bulk emails? I noticed it's the BBB and they send a lot of messages people might mark as spam. The error from Google says that their antispam system has marked it as spam. Is there any content of note in your messages that are getting blocked? Anything like links in a signature to URLs that might be in a blocklist? One thought to get that escalated is to email a Google Workspace paying customer and have them make a support request about the issue.
