[comp.mail.uucp] novice question re mail maps/bang paths.

jfsenior@vax1.tcd.ie (Semolina Pilchard.) (08/15/90)

People of the net.

I wonder could someone do me a favour?

I am looking for information about using uucp mail i.e. how to use 'bang -
paths' and how to use/ where to get mail maps?

Can someone point me in the way of some material I should read?

Thanks in advance...

	here is a fairly simple example of using "bang paths".

	for mail:

	        mail machine1\!machine2\!login

	for files:

		uucp machine1\!machine2\!/path/file


	the backslashes prevent the ! from being expanded. another way
	to accomplish this is to enclose the entire expression in single
	quote marks 'machine1\!machine2\!/path/file'.

	"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.

Probably a wasted effort.  If the smart site is willing to forward for you
it should also do the path lookup.  You should have been able to send
to smart_host!end_host_or_domain!user and let the mailer on the other
machine do the lookup using its current paths data.

	The "big project" I had at that time was routing email around the
	world.

	I wanted to specify a whole path (mail host_a!b!c!d!e!f!host_a!my_login)
	to wrap it around the world.

	At the time, they didn't have the pathalias stuff hooked into their
	mailer, just available to users. 

	But, your point is good. Just find a smart site and hand it to them
	if you can't get pathalias and comp.mail.maps on your host.

This is one reason why rabid rerouters exist and are welcomed.

This is one reason why rabid rerouters are routinely cursed.
Consider trying to debug a mail problem among b!c!d!e!f!host_a from host_a
if b,c,d, or e is rabidly offisious.

Do you think we could condense the next 37 rounds of this argument into
3 or 4 keywords?  How about a monthly posting of the arguements of both
sides?  The only excuse I have for continueing is to try to limit the
number of converts the Other Side makes among newcomers.  I have no hope of
reclaiming those who have already chosen Evil.

Like I said about a month or so ago, there are some problems with
Rabid Rerouting, and debugging long EMail paths is one of them.  Note
that it is not impossible; just that it is more difficult.  In general
you can look at RECEIVED lines to figure out what happened to a
message.  If a message is dropped without error, it gets a little more
complicated, but not impossible.
