Can somebody PLEASE send me a explanation of all the builtin flags that
can appear in a "F=......," field of a mailer definition.  According to
the SunOS4.0 manual I have here, I understand:-

	f (or r) = pass sender name to mailer
	S	 = don't setuid to another user when calling this mailer
	l	 = mailer will perform local delivery
	s	 = strip quotes and backslashes
	m	 = can batch mail through
	e	 = expensive
	C	 = tag source domain onto outgoing 'From:' data

There are also flags relevant to the H?x? bits of header definitions,
but I know which ones they are, and there are a few flags (eg: 'n', 's')
which I don't have documented.

However, my main problem is that we are a multihost site, with one
gateway running Ultrix 4.0 (Sendmail 5.57, zilch documentation) talking
to the network.  Our Ultrix came with the UK sendmail compiler v1.4
(v2.1 is better looking, but I can't afford to play with it at the
moment, so I'm using the dealer-supplied stuff).

I'm hand-tooling a client sendmail.cf to send *all* mail via "[IPC]" to
this one gateway, which fires it off to the world using a UKsm-generated
sendmail.cf file.

Problem/annoyance: Internal mail from a client, passed to the gateway
and delivered to the user gets a unix type

	From <user> at <ctime format date>

but DOES NOT get

	From: username blah blah <address>

as is supposed to be generated in the headers by

	H?F?From: $q

-this really freaks Rand-MH out! If you do internal mail on the gateway
however, the desired "From: blah" DOES appear in the mail headers.  I
think therefore that something is wrong in the client's sendmail.cf
file.  I define the the client->gateway mailer thusly:-

	Metherlocal, P=[IPC], F=fnsmuCFDMRX, A=IPC $h

		any ideas, please !!! Thanx in advance.
