I donʼt think itʼs correct: previous to this change, telling gnus to
sign an email would result in gpg using your default key, which in 99%
of the cases is the right thing to do. The 1% know how to override it.

Hence my strong desire to set
mml-secure-{smime,openpgp}-sign-with-sender to t. Or do the query
thing I proposed a patch for earlier. Or update the message.

In that order of preference, I think.

Thatʼs a separate issue. And proobably only affects 1% of the 1% :-)
