Yes literally it threw an invoice from AWS into spam recently. Regularly throws financial docs into spam. Like you, i have a problem with false positives not false negatives. I brought it up with support once and the domain was failing DMARC. Headers from the AWS email that has a spam score of 9.1! I don’t know much about email but something must be wrong there on Fastmails side. x-sieve: CMU Sieve 3.0 X-Spam-known-sender: no X-Spam-sender-reputation: 500 (none) X-Spam-score: 9.1 X-Spam-hits: DCC_CHECK 1.1, HEADER_FROM_DIFFERENT_DOMAINS 0.249, HTML_MESSAGE 0.001,
