Sure it can.  It could get the domain from mail-host-address.  We
could also create another variable specifically to control this.

The current behavior, as you described it, is not much better
security.  It is unpredictable in practice for the user.  However,
I am not sure how much security issue there is in sending A a message
encrypted for B.  Nobody can decrypt that message.

I have seen reason to think that the current behavior doesn't match
what you described.  I entered "To: rms" and encrypted the message.
It recognized that was me, rms@HIDDEN, and encrypted with my key.

It did this even though my key does not list 'rms' with no host name as
an address (as far as I can tell).

gpg --edit-key rms@HIDDEN gave me this:

    pub  4096R/2C6464AF2A8E4C02  created: 2013-07-20  expires: never       usage: SC  
	 ...
    sub ...

    [ultimate] (1). Richard Stallman <rms@HIDDEN>

If the key had another address, wouldn't it be listed there?

In addition, after I run the encryption command,
plain 'rms' has been edited into 'rms@HIDDEN'.  How does it know
to make that change?

Emacs cannot possibly know that when you send to "arthur", that that
email will eventually end up going to "arthur@HIDDEN".  It could guess,
but guessing in an security context is a no go.

So if you want to send somebody secure messages, you have to tell Emacs
what address the mail is going to: You can't just say "arthur".

We seem to be failing to commnuicate.  My From header always says
"rms@HIDDEN", but we're talking about the address I am sending to --
in the To field.  Is that what you mean?

The behavior that you describe is totally unpredictable for me because
it depends on data I don't know, and have no other reason to know.
When foo@HIDDEN sends me a key, I don't notice what other addresses
that key covers.  There is no reason to.  And those alternate short
addresses are not listed by epa-list-keys.

If I have a key for 'arthur@HIDDEN' and another for
'arthur@HIDDEN', it is a nuisice for me to check which one, if
either, lists just 'arthur' as an address.  Especially since when I
send mail to 'arthur@HIDDEN' I may not even remember I know
'arthur@HIDDEN'.

When I send mail to just 'arthur', that is equivalent by default to
'arthur@HIDDEN'.  I often omit '@gnu.org' knowing this.

Encryption should do the same thing: treat 'arthur' as short for
'arthur@HIDDEN'.  That way it will always encrypt for the person that
the mail is going to.

I'm not sure I understand.  I think it does do something completely
predictable -- choose the key ring entry that matches what's in your
"From" header.  No guessing involved.

That is totally unpredictable _for the user sending a reply_.
There are various possible ok things to do, but not that.

Please make this case do something predictable.

I don't think any security-related software should be guessing based on
incomplete email addresses.  As far as I can tell, it requires a
complete match, which I guess means you have a key for "martin" (without
a domain name) in your key ring.

Choosing this is the right thing to do, I think, so I'm closing this bug
report.

I have a public key for martin@HIDDEN and a key for another martin at
another host.  When I encrypt a message to `martin' -- which means, in
my case, `martin@HIDDEN' -- epa-mail-encrypt picks the other martin.

epa needs to know the default mail hostname so as to pick the correct
Martin.  It can get that from the value of user-mail-address, and
maybe have other ways to specify it.
