Uh, apparently, many automated systems generate malformed MIME messages and so we need to handle them somehow instead of rejecting.

Thank you for the quick reply. I’ll open a ticket with the vendor.

Status update:

First reply from the vendor before doing some test suggested by the vendor:

"The email report function implemented on our AP follows the basic standard."

Then went on to do the suggested test with the same result as before.

send using gmail => gmail - works send using gmail => Maddy fails forwarding the received mail from gmail to Maddy via Apple mail client works disable TLS on AP use port 25 => no send - no receive as expected.
