No, it is SCOSv2

It is part of a SCOSv2 message.
To decode the message you have to look at the
Message-IDs first part, which is crockford base32
encoded. Hence the Subject: name.

Or one can just search the key space, which is small. That works well
enough because most SCOS texts are recognisable language.
So I wish you the same, Stefan.

Thanks, but how does this work in general? I mean if someone writes a
SCOS message cracker, will it print to stdout all decoded tries and then
uses, grep like, some key words, so that the user can see the plain text
in one of the decoded messages, which he has to go through?

Thank you.

Thanks for the info, I thought there would be more possible keys.

This was only a test with M-IDs, but I understand what you mean.
