Re: Hide internal address (Postfix)

Steven makes a good point and this is true for many antispam software being used.
On the other hand if the IP address that is being published is of a private network, like 10.x.x.x or 192.168.x.x, the smart antispam software won't accept it either.

If you do so, aren't your mails rejected by some mail servers because they consider that you have an illegal or incomplete header?

hello chris,

this is how I've done it:

add to

header_checks = regexp:/etc/postfix/header_checks

in that file you put

"# Header checks file
#    /^Subject: Internet Sic Codes/  REJECT
#    /^Subject: ADV /
/^received: / IGNORE
/^X-Sender: / IGNORE

that removes the the sender-header before you deliver it to the internet. works great besides eurora clients.

Hi everyone!
Iam using Postfix for mail delivery.If somebody inside my network send mail outside the network, the recipient can see in the message header the internal address of the sender host.I would like to hide it, or replace it with the external address of my router.
Any suggestion?
best regards
ps.:i appologize for my poorly grammar
