[PLUG] DKIM authentication with alpine

[Rich Shepard]

   I'm adding DKIM to my postfix installation and have /etc/opendkim.conf
identifying my domain as the sender. My web searches on how to set alpine to
use authentication fails to find anything newer than 2009 (which has a dead
link to the dead UDub alpine mail list). I also see nothing in alpine's
setup about authenticating outbound mail; it may be there and I don't
recognize it for what it is.

   Pointers and suggestions are solicited.
