hi simon,

i never found the mail anywhere -- it passed amavis, so no traces there,
and the mail couldn't be delivered via LMTP, so i think it just got
discarded -- postfix didn't have an address to send a bounce to.

the source of the mail (in my logging) is real -- it's HP's licensing
department. i am going to tcpdump -s0 and capture to a file so as to
watch the entire conversation. i'll send you a copy off list.
