I'm receiving SPAM from my own address.
Checking server logs, user is not authenticating and the only way this
spammer can play a trick is by sending an email to its own address (ie:
from raf...@mydomain.com to raf...@mydomain.com).
Is there a way to avoid this practice ?
on your server: use smtpd_sender_login_maps
on other servers: implement SPF,DKIM and DMARC for your domain.
note that some servers don't enforce DMARC, so mail from your address
may still appear on the internet.
