The more content the message has the more common the block but its end user "eyeball" conversational messages and not managed content. Even content such as "This is a test message" is blocked now. All blacklists are monitored, and we are clear on all Ips. Being end users we get a compromised account every couple of weeks but they are ratelimited to 100 messages and handled within 6 hours usually. No blocks from any other providers.

Does the message have content that is considered harmful by Google? Do you send from IP ranges that are often used by spammers? Check uceprotect Level2/3 as an indicator. _______________________________________________ mailop mailing list mailop@mailop.org https://list.mailop.org/listinfo/mailop
