I recive lot of email that are trash it, I wannt to block them, for example *@domain.com, and this configuration is distributed to all the mail in my server. I use Centos 4.4 with ISPConfig.

Thanks a lot.

 

You can do this in /etc/postfix/restrictions

1) add in the file restrictions (it's in /etc/postfix/) the following

Code:

domain.com		REJECT
anotherdomain.com	REJECT

2) Now run

Code:

postmap /etc/postfix/restrictions

3) Now reload Postfix with

Code:

postfix reload

After this any email from domain.com and anotherdomain.com will be rejected.

Please note that everytime when you add, or remove a domain from restrictions, you WILL need to do step 2 and 3 again!

 

But this File RESTRICTIONS dont exist, can I create file???

 

But this file RESTRICTIONS don't exist in /etc/postfix, can I create file????

 

yes you can, but in that case you will need to add the following to /etc/postfix/main.cf

smtpd_sender_restrictions = hash:/etc/postfix/restrictions

You will need to restart postfix again after this!

 

Ok, I do it. If i wannt to restrict a email, ex. [email protected]. Can I add to file restrictions????.

 

I see that many email have diferent domine name, but in the body of the message have a many same words, how can I create a rule for restrict email with the same body and/or subject???. For example, subject: VIAGRA

 

You could use header and body checks:
http://www.postfix.org/header_checks.5.html

 

I could already make work the Header_checks, but the Body_checks I have not been able to. They could help me giving me a simple example: For example, Body: "Sale of Software", thank you.

 

body_checks work exactly the same way as the header_checks.

 

But in the header_checks, put for example: I write "/^Subject:.*viagra*/ REJECT", if you see "Subject". But how need to write for say "Body"???
"/^Body:.*viagra*/ REJECT" ????

 

The: "Email reporting spam detected" is only for a note. You can remove it if you like
