I know that there is the TLS certificate file missing. I'm plainly not sure whether it is missing on my system or on the system the mail is sent to. I suspect it's the other system since other known messages in this format always tell an error on the other side, but I'm plainly not sure about that...

Could someone please tell me for sure that it's the other system? ;-)

dig -t mx otherdomain.de to find the MX.

telnet MX 25 Trying aaa.bbb.ccc.ddd... Connected to MX. Escape character is '^]'. 220 otherdomain.de ESMTP STARTTLS <-- issue this command 220 Ok <-- if this is the response then you're ok.

If it says "454 TLS missing certificate" instead of the 220 response then it's a problem with their server. Lately I've been getting a lot of these, I check the whois, call the SA and they take care of it. Lots of people are running servers advertising TLS without a certificate.
