	"bang path" stands for an addressing syntax that specifies the path 
	from your host to a remote host and user with '!'s (bangs) used as
	a separator.

	Example:  	att!cblpf!joe
			Central.Sun.COM!jeff.jones
			att.com!joseph.t.judge

	This is different from the domain style address, which is the:
	user@full.host.name.  Where, full.host.name is the full "dotted" 
	domain name for the remote host and user is a local mailbox or
	local address. These addresses must end in a valid top-level domain.

	As for the maps:

	What you need to look at is the 'pathalias' routing database generator
	(by Steve Bellovin and Peter Honeyman).

	The info posted to comp.mail.maps is passed through pathalias, it
	generates a database of paths to the send hosts - relative to your
	site.

	The comp.mail.maps files are kind of boring and useless if you don't
	have something to compile them into hop1!hop2!hop3 

	What I did, in college, was have a friend at that closest "smart"
	site send me an ascii copy of his "paths" database.
	
	It looks like:
	"hosta		host1!host2!host3!hosta!%s"

	Then, if I need to send somewhere, I grep it out, send the email to
	"that_smart_host!whatever_path!user"

	This helps overcome that big problem with using bang paths. That is,
	you, the user, *has* to know the full path from here to there and
	the connectivity is relative to your local host.
