1) The timezone is supposed to be where the human is, not necessarily
where their server or e-mail address is.

2) That timezone is infact the timezone of the mailing list software.
It insists on destroying virtually all the headers when processing a
mail message, much to several people's annoyance (and the generation of
some considerable confusion).



I'm still not clear on the original point though.

For the dual homed (and additional virtual interfaces) machine, surely
the nmbd is samrt enough only to send out any given response packet onto
any given subnet exactly once, no matter how many interfaces it has open
to it?  To do otherwise is surely nonsense.

So, assuming it _is_ doing that, where is the extraneous response coming
from?

With two subnets on the same wire, a machine in only one of the subnets
with a lousy IP stack might see the broadcasts from the other subnet,
and log them  (older versions of SunOS did this) but even this doesn't
explain why two identical packets arrive.  The dual-homed machine must
have sent two identical packets, _on_the_same_subnet_, and it's this
behaviour that I can't fathom.
