I'm still trying to figure out how the domain system works, in
the meanwhile .. my thanks to all who have posted or mailed explanations
to me.
Here is an example of some of the crazy things that can happen
to the mail when mail handlers mung up the "To:" or "From:" lines. As a
background, I received a message to "marc@zebra.???.???" a couple of weeks
ago. (I have forgotten which domain.) I sent it back to the original
sender so that he could readdress it. (Yes ladies, it was a 'he'.)
Since then I have received three messages from MAILER-DEMON's at
somewhere or the other. I was able to observe that one of the earlier
ones was bounced by my 'mailx'. The third is listed below.
o What am I supposed to do with these?
o How can I avoid clobbering up the system with these crazy messages?

Note 1: This is the time that the message was received here but it
illustrates one of my pet peeves. The audacity of the writer
of my 'mail' program to think that the world revolves about the
eastern u.s. time zone. If they can't use the built in
conversion routines to produce the local time, they should have
at least used the the universal standard of GMT (or UTC as it
is now known.)
Note 2: This is my friendly neighbor who is my only path to the net.
Note 3: Did the address get munged here or didn't it?
Note 4: They had it correct here.

It's perfectly legal to give the date in EDT, as long as you put "EDT" (or "-004") in the proper place. I could also use "EST" (or "-005"), or "PDT" (or "-007"), or "-009" (if I was in Hawaii), or whatever I want. Mailers should be able to figure out "EST", "CST", "MST", "PST", and their equivalent daylight-savings-time versions, along with anything in the form "[+|-]nnn". RTFRFC (Read The F***ing RFC). (I could say something about the "audacity of the writer of Unix to think that the world revolves around GMT", but I won't. As Andy Tanenbaum says, "The nice thing about standards is that there's so many of them to choose from.") -- Marc Unangst UUCP smart : mju@mudos.ann-arbor.mi.us UUCP dumb : ...!uunet!sharkey!mudos!mju UUCP dumb alt.: ...!{ames,rutgers}!mailrus!clip!mudos!mju Internet : mju@mudos.ann-arbor.mi.us
