So, my message to the IETF list produced the usual cascade of "Out-Of-Office
Autoreply" messages, fromn people I've never heard of, and who *certainly*
weren't in the "To:" or "Cc:" fields of the header.
I'm going to withhold the names of the guilty (they were all from completely
different companies, BTW), but I note that for all except one, their message
header included:
X-Mailer: Internet Mail Service (5.5.2653.19)
Anyone know whose email software this is? (Since nothing else seemed to
display this failure mode, I suspect it's specific to this particular software
that its default configuration is to send autoreplies to all messages, even
ones not directly addressed to the sender - if it even recognizes the
difference.) The odd man out said:
X-Mailer: Internet Mail Service (5.5.2651.58)
which I guess is just a slightly older version of the same thing. (I did see
one with an:
X-MimeOLE: Produced By Microsoft MimeOLE V5.50.4133.2400
header, which leads me to guess whose software this is, but before jumping to
that conclusion, let's see if there's definitive knowledge.)
