Yes, it was spam, and it was caught by SpamAssassin. It was some bitcoin
plot or something.
The characters were not anything I could read, and the few I could make
out were of a south-east asian descent.
My concern is that the email APPEARED to come from me! I was listed as
the sender.
I examined the message source, against other valid emails sent by this
user, and there wasn't anything that I could clearly see as the reason
or how this was done. I have checked against password hacked sites, and
the email password of the user doesn't seem to be compromised. I have
only received maybe 2-3 of these emails in the past year, and only on
this user--all caught by spam assassin.
I guess I am concerned, because I don't how this happened.
Here is my best stab at where the problem could be.
Here is a clean email:
Received: from example.net (unknown [192.168.1.10])
by mail.example.com (Postfix) with ESMTPSA id D7C3F1980059
for <do...@example.com>; Mon, 25 Oct 2021 03:42:29 +0200 (CEST)
Here is a non-clean email:
Received: by mail.example.com (Postfix, from userid 1005)

Just trying to figure out if my system is compromised, thanks!
