Hello,
I am receiving spam, where the "header from" is my actual email (ie,
the
email that this spam is delivered to)
The "envelope from" that I see in postfix logs is some random email.
What mechanisms are there to reject such messages, which use my email
address as sender ?
SPF helps against forged envelope senders. DMARC helps against From:
header forgery.
Can I reject messages that have different envelope from and header
from?
Or what would be the best approach ?
Examine this message. Is it spam?
