Receiving fake e-mails like from distribution list

Post by brunohpg »

Hello,

I'm getting fake emails like it's from an internal distribution list.

The email "correctly" departs from:

Code: Select all

Received: from bos7.mirandasilvafolheados.com.br (bos7.mirandasilvafolheados.com.br [89.44.193.109])
Received: by bos7.mirandasilvafolheados.com.br (Postfix, from userid 33)
Although:

Code: Select all

From: list@domain.com.br
And I get it as "list@domain.com.br".

I had already done the procedures in:
https://wiki.zimbra.com/wiki/Enforcing_ ... ername_8.5

but the problem remains.
Can anyone tell me how to block this type of email?
