I am using postfix, but someone trying to hack me and sending spam email to get paid, So far I have blocked emails using headerchecks and bodychecks but now he is sender spam emails in the Chinese language. with same my email address to me. I wanted to block the same emails from my own address to me please help.
Hey friend,
Personally I enjoy rspamd for filtering spam with Postfix:

That said, there's only one way that I can think of for a "one size fits all" fix on this. Are they sending these emails from a specific server, or through a large mailing service? If they're sending from one server, grab that server's IP from your logs and black hole it like this:
ip route add blackhole 1.1.1.1
(Replace 1.1.1.1 with their server IP)
If it's always the same sender, I'm pretty sure this still works, despite it's age:
