Thanks for your code.  It works here too and is much appreciated.  

[Off topic: I'm working through the mime-security customisation
at the moment.  As far as I see now mime-security proposes all
ultimately trusted keys for signing and does not filter this list
of keys with the email address in the From: header.  As a mutt
user I'm used otherwise: mutt is configurable to only show a key
selection menu if there are more than one key which fit the
relevant address -- otherwise it uses this only one without
further ado.]
