  Ok, I was clear about that part.

  I would not do that, but since the original question in this thread
was about having to change the prefs because they didn't show a
compatible algo (and AES256 was required), I thought _maybe_ the people
refusing to encrypt with 3DES had disabled it. But I suppose they
checked the key manually, and noticed AES256 was not listed.

  It was just curiosity. By the way, is it possible to disable some
other encryption algo, but without forcing GnuPG to use a chosen algo? I
mean... lets suppose I don't want to use AES, but I'm ok with twofish,
3DES, and Camellia (any of there would be good enough).

  Yes, I still remember that post ;)
