This is email you're sending, but certs are inspected by sending not receiving systems. Your self signed certificate has no bearing on delivery of outbound email. You're showing an irrelevant log entry for email re-injection into amavisd-new for scanning. And no evidence than anyone is rejecting your mail, In other words, you're so confused, that you're babbling nonsense, but it seems to make sense to you. You need to forget everything you think you understood and start again from scratch. > Lovely, lovely. I CAN understand this. Afterall, secure communications is > my day job. But I don't like it.
