D'oh, I can't believe I forgot that.  Qmail.

Yes, that's right.  List posts are working fine.

Hm, now this *is* interesting.  Please forgive me, I just started using 
Mozilla for my mail and only recently finally figured out how to view 
really really all the headers.  Here they are:
Return-Path: <yogabc-admin at yabc.ca>

Note the utter and complete lack of any Date: header whatsoever.

It is odd that neither Mailman nor the local MTA is providing a Date: 
header though.

Aha!  Same result.

Mutt, bless its doggy heart, handles it anyway.

Nothin'.  Zero.  Zip.  Nada.  I really need to switch to Postfix.

:-)  "date" shows the correct date, but I thank you for your 
thoroughness.  Seeing now that it is indeed qmail that's handling all 
this, via the usual SMTP path, I'm baffled that it has decided to stop 
putting in a Date header.

Possibly too, this is a very subtle y2k bug within the mozilla mail 
client, where it was handling stuff before 11/31/00, but turned over to 
'69 on 12/1/00.

Irksome, is what it is.  Ah well, thanks kindly for your help.
