Hi all
I have an internal mail-server. Use the astaro only for relay.
The case is:
If I connect in a mail server (yahoo, aol...), I get to send a mail for the domain DOMAIN (domain.com.br) as an internal user. This mail, goes by the smtp-proxy of DOMAIN and it proceeds for the user of that domain.
Like this, connected in any mail-server, I send a mail for janilson@domain.com.br with the user jonhhrs@domain.com.br. This mail goes by the smtp-proxy. It arrives for janilson@domain.com.br that thinks that was sent by jonhhrs@domain.com.br.
Connecting in any mail-server:
telnet 200.214.190.1 25
mail from: janilson@domain.com.br
rcpt to: jonhhrs@domain.com.br
data
Mail test
.
Question:
How to build a rule in the spanassassim to block this activity?
I need to filter only the domain!
If "From: anybody@domain.com.br" "to: anybody@domain.com.br" DROP
Thanks.
