The problem with the sender address spoofing.

[evilmorte]

There is a server with the address X.X.X.X, and many domains with diferent ip's (exim, DirectAdmin).
In case of sending letters without spoofing, in technical writing headlines prescribed the correct domain and the corresponding ip address (looks like many SMTP). But if the sender makes spoofing the sender address, the message headers specified ip address of the server, an error SPF and DKIM are signing letters. Cant find solution, please help!

Solution for what? How to bypass SPF and DKIM check with spoofing? If yes, then you are definitely on the wrong forums. Here we find and discuss ways how to stop spam on servers with directadmin, but not how to send it.

I'm talking about a situation where one of the domains the user starts to send spam with the substitution of the sender, and are affected users who have accounts on the primary domain / ip. In fact, I'm talking about the fight against spam.
