Hi all

Auth:   by a Spamtrap on 2001:4060:dead:beef::1907:2 25 pretending to be an 
open relay for jodyyw...@blacklist.woody.ch; Mon, 27 Mar 2023 07:22:56 +0200

jodyyw...@blacklist.woody.ch is a spamtrap. I can guarantee, that this
email address is not being used for any other purposes and has never
been subscribed to any newsletters or similar.

From the 'username' i more suspect that this was generated and verified
'valid' by some script checking my spamtrap to accept emails to this
destination.

Such a 'confirmed' spamtrap hit immediately causes the sending IP to
get listed in the SWINOG blacklist.
I also looked at the email content.
It is spam, sent via PHPMailer relaying it's payload via Office365
submission servers.

Unfortunately, this massively affects other Office365 customers. But
they complaint because we (operating the SWINOG blacklist) block them,
they don't complaint to Microsoft for being the source of the issue and
find it hard to address such issues with Microsoft.

What would be the best way to address such issues for Office365
customers?

Mit freundlichen Grüssen
