I dunno why the -a option wasn't used.. in fact this is the first time
I've ever heard of that option and my first thought it was something
on a specific version of UUCP that I don't have access to. But I just
checked on Sun OS 4.1, SysVr3.2 and 4.3-Tahoe, and it was on all of 'em.
Sigh.. I guess that's my new thing to learn for the day, I might as well
go home now ;-).
As to whether this is a problem? Sendmail sites generally have the
UUCP originator be `daemon' so I don't see how that's very different
from MMDF sites having the originator be `mmdf'. Can you explain further?
Why should the UUCP originator show up in From lines? (Situation
which I am imagining at this point: sender at an MMDF site. UUX/UUCP
originator is `mmdf'. From at originating site says `user'. Gets
delivered elsewhere. In order for From line to say `mmdf' that
has to be changed somewhere. But all the rmail's I've seen simply scan
through From's and >From's and concatenate strings. So
where would this change be made?)

Yes.. we've had a little discussion recently (this week) about how
the Host Requirements RFC relaxed RFC-822 a bit such that the former
requirement for:
From: phrase
now doesn't require the phrase. (e.g. "From: " is enough).
But the address parser won't work with this format because it sees '<'
as the beginning of something to read in a list of addresses from a file.
So, anyway.. yes, there's been some activity. You should probably contact
mmdf2-request@relay.cs.net again..

er.. ah.. I *am* an MMDF worker.
If I were to forced to come up with a h{i,y}st{e,o}rical reason for it
not being discussed out here it would be:
-- The previous groups of workers are/were from the Arpanet Mailing List
tradition which tends to look down upon Usenet. (Indication: The `send'
and `resend' programs (for sending and re-sending mail) in MMDF assume
the ~/.signature file is suitable for the `phrase' part of the From:
line.. take a look at my .signature below ;-))
-- The traffic on the mailing list has never been heavy enough to justify
a newsgroup.
-- There is a generally low opinion of MMDF which, as far as I can tell,
derives from Olden Days when MMDF was truly buggy. Nowadays it is very
unbuggy, except in the documentation which is a bit lacking (sigh) ..
at any rate the rep isn't quite deserved.
I think I had another reason but it seems to have slipped away.. ohwell.
comp.mail.misc is just as good a place as any to talk about MMDF. If the
traffic warrants we might just be able to wangle a newsgroup ;-).
