I tried the same procedure of signing and sending a mail to myself but
this time with an email account where the MTA didn't convert the
content-transfer-encoding from quoted-printable to 8bit and this time
neither the archived nor the received mail verified correctly.

I have done some research and my working theory is that digitally
signed messages cannot be quoted-printable. Is this correct?

In that case the problem is that when I include Swedish signs in a
message, emacs sets the content-transfer-encoding to quoted-printable
which screws up the signature. When I send it through an MTA that
converts the content-transfer-encoding from quoted-printable to 8bit
everything becomes ok again.

What I have to do then is to make sure that emacs sets the
content-transfer-encoding to 8bit whenever I send a digitally signed
message. There is a variable called
`mm-content-transfer-encoding-defaults' but I feel that I do not
enough about this yet.
