I feared so after I read up on all this stuff.
Wow, is it just me or does anybody else consider this a major design
flaw of the whole setup?
For two reasons:
- After decades of IT, how can one still design software that is
absolutely unforgiving to people's stupidity in a critical area.
That's like being able to close a window of unsaved work without
being prompted to save.
- It is so easy to make life miserable for somebody else. What would
prevent me from picking any e-mail address that isn't mine and upload
dozens of keys to the key servers, maybe even give them misleading
comments like "current" etc.. If anybody were then looking for the
public key to joesmith at hisdomain.com, there would be a useless mess
of keys without telling which one is correct to use. And worst of
all: Joe Smith has no way of fixing the situation, even if he is
legitimate owner of the joesmith at hisdomain.com e-mail address.
It strikes me, that GNU-supporters would bash MS (or for that reason
any vendor of proprietary software) for dishing out once more a
thoughtless, immature and insecure software design.
I understand it must not be simple to revoke or disable keys. But it
shouldn't be impossible either, especially in the light of anybody's
capability to put public keys under my name on the server.
Am I missing something?

Well, my issue is not so much with the keyservers. I guess with
faster and more hardware this scheme could be maintained for decades.
But if the keyservers are not directories to look up public keys,
then what are they? And if they are meant as directories, how good
are they if they are flooded with garbage keys.

Can gpg use this keyserver? It is listed in the settings of my MacPG.
Is using this server recommendable for everybody?
Thanks for your answers, David.
I'll do some more reading how to deal with this. This page has a
suggestion to work as good as possible with the situation:
I'll have to think through it when I'm less tired. All this key stuff
is still very foreign to me.
