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@gnu.org, 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@gnu.org gave me this: pub 4096R/2C6464AF2A8E4C02 created: 2013-07-20 expires: never usage: SC ... sub ... [ultimate] (1). Richard Stallman 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@gnu.org'. How does it know to make that change? -- Dr Richard Stallman Founder, Free Software Foundation (https://gnu.org, https://fsf.org) Internet Hall-of-Famer (https://internethalloffame.org)
