What about this, then? Does this say anything about why
there's always
two .dat-files attached together with the encrypted
attachment?

--=-FBjrxYQ2/8R5tscH+TLU
Content-Type: application/pgp-encrypted; name="dat.asc"
Content-Disposition: attachment; filename="dat.asc"
Content-Transfer-Encoding: base64

And if so, what does it tell me?


As the "Content-Type:" says, that's the PGP encrypted
attachment.

I don't know why there are two .dat files.

If you want, forward the mail (as an attachment) to me and
I'll have a
look at it.  But it won't be immediately.

P.

Everything is working just fine now! I'm very pleased with
Evolution.
But what does it mean when it says that the signature is
valid, but
cannot confirm the sender (I don't know the exact wording in
English)? 

I think it is the same what I see here:
Signatur existiert, jedoch wird der öffentliche Schlüssel
benötigt.
or
gpg: Signatur am Sa 20 Feb 2016 16:56:34 CET mit RSA Schlüssel,
ID
7C174863, erfolgt.
gpg: Unterschrift kann nicht geprüft werden: Öffentlicher
Schlüssel
nicht gefunden.

I haven't checked the English UI but it could there sound like:
Signature exists but the public key however is
needed/required. 
or
gpg: Signature at the Sa 20 Feb 2016 16:56:34 CET with RSA key,
ID
7C174863, is carried out. 
gpg: Signature cannot be checked: Public key not found.

Oh, I was expecting this from others, like when I don't trust or
sign
their keys. Hm. I didn't expect from my own private key. So I
have to
sign and trust my own key too! Like gpg --sign, and level of
trust. I
wonder if I should trust myself with level 5 ... ;)

So your expectation is right. Me - as OTHER one - can't trust the
sender
is really YOU as far as not having your public key to check if it
fits
the private key you signed your mail with. Keeps me hanging on if I
don't know where to get your public key, except you would be so
kind to
send it to me. Easiest way was to include it in your mail
somewhere.
I don't know, how Evolution exactly handles this, but the
mechanisms of
PKI are simple at last ...

What happens if you run gpg --recv-keys 7C174863 ? That will give you
my
public key, right? You can also type in my email address in
gpg.mit.edu.
But I'm really curious if my public key-block is supposted to be
attached to my signature? The 7C174863 is already there, yes? I don't
know what people usually do. Probably compare the fingerprints with
each
other before they sign and trust. How Evolution works, I really don't
know. 

My key weren't confirmed in my sent messages before I trusted my own
key. So I guess that's what other people that trust me have to do
too. 

Your signature should look like this one

Your signature looks like this:

gpg: armor header: Version: GnuPG v1
gpg: Signature made la. 20. feb. 2016 kl. 21.41 +0100 CET using RSA key
ID 0D20E541
gpg: Can't check signature: public key not found


Mine looks like this:

gpg: armor header: Version: GnuPG v1
gpg: Signature made la. 20. feb. 2016 kl. 21.55 +0100 CET using RSA key
ID 7C174863
gpg: using PGP trust model
gpg: Good signature from "Stig Roar Wangberg <srw openmailbox org>"
gpg: binary signature, digest algorithm SHA256

Probably 'cause it's signed and trusted. And probably yours would look
like that to me too, if I were to sign and trust your key.
