YAMN client outfiles are the same as Mixmaster outfiles. One can generate
them with the client, so that the outfile (a complete Mix Message) is written
to the clients pool directory. This allows one to create Remailer messages
on an offline computer, in case he / she downloaded the required stats and
pub keys with an online computer and then transfers those files to the offline
computer.

Thats what I did, yesterday. :-)

Ok, like I said, I have my solution. The problem for me was that Mailchuck
sends messages as MIME email and not as plain ASCII message bodies, thus
messing up the outfiles, pasted into the message body of a Bitmessage
client, once they arrive at Iria.

For my Exit Bob I don't need a signature strip-off solution, because I
made a mistake in thinking, i.e. Iria already strips this signature.
