I cannot verify them and as far as I know, Enigmail cannot verify them.

We are talking about signing, not encrypting nor decrypting?

I am automatically receiving missing keys from keyserver and you can
get my key by running

Enigmail and GnuPG don't automatically receive keys unless you
configure it to do so.

With Enigmail you go to expert settings and write the keyserver where
to receive keys to the second box in that tab where you specify
keyservesrs.

With GnuPG you have keyserver line and something like below in
~/.gnupg/gpg.conf:

I told how to receive key above.

The key appears as UNTRUSTED, because you haven't (l)signed my key and
you shouldn't do it unless you meet me and verify my identity.

I warmly recommend to receive missing keys automatically :).

Note that I am currently on Debian Unstable (Sid) and this might be
little outdated, because I don't have time to upgrade and same is with
replying to emails. I see that this email where I am replying to was
sent three days ago.

NOTICE! I am on mobile broadband with very limited time, so I cannot
read emails very much.
The best time to contact me is probably week ends when I have better
connectivity with good luck.
