Hi, sporadically I get the error Unexpected record type 'X' at offset ... and the message is moved to the corrupt queue.
E.g. postfix/smtpd[19574] 010EDD6443: client=unknown[1.2.3.4] postfix/cleanup[98995] 010EDD6443: message-id=<> postfix/qmgr[63719] 010EDD6443: from=<sen...@sender-domain.com>, size=14197, nrcpt=24 (queue active) postfix/qmgr[63719] warning: Unexpected record type 'X' at offset 17542 postfix/qmgr[63719] warning: saving corrupt file "010EDD6443" from queue "active" to queue "corrupt" The message looks OK to me. It is multipart/mixed with multiple recipients. The offset is always at the end of the message. postcat -do 010EDD6443 ... 17481 78 ----boundary_641_fc5671dc-1c1d-438e-a827-019b96ffe19b-- 17538 78 17540 78 17542 88 *** HEADER EXTRACTED 010EDD6443 *** 17544 69 *** MESSAGE FILE END 010EDD6443 *** Postfix version is 3.7.0 and runs on FreeBSD 12.3. I have no idea what HEADER EXTRACTED means an why it appears or why it shouldn't. Messages were sent with different email clients. So what could be wrong with the message?
