For mailing lists, "From" is screwed up to evade SPAM filtering.  This is 
not an Alpine problem.

To prevent SPAM, most mail servers have adopted a rule:
only accept mail "From" an email address if the server sending it is 
authorized to receive mail from the domain of that email address.

This breaks mailing lists: the "From" would naturally be the email address 
of the person who submitted to message.  For example, in your messages 
case, bret at busby.net.  But the MX record for busby.net says (only)
busby.net can handle mail for you.  So the mailing list program sends
your message with an rewritten "From": 
	Bret Busby via Alpine-info <alpine-info at u.washington.edu>

That's why a simple reply doesn't do what you want it to.
