Qmail Hide IP in Headers (for relay clients) Patch

Here is a link to a patch i have Written,

It will hide your Private or Public IP in the email Headers when you are
sending Mail as a Relay Client.

This is very handy patch for people with Mail Servers that are behind a
Firewall / Gateway
and where all your local lan clients are not wanted to show there IP in the
Mail that they send ...

Seems to work flawlessly (Considering i dont know how to Programm in C, Just
hack. ;-)

Feel free to add changes or make suggestions =)

Thanks,

No patch at all is necessary. Simply set TCPREMOTEIP and TCPREMOTEHOST to empty
strings in qmail-smtpd's environment when the connection comes from one of your
internal addresses.

For example, if your internal network is 192.168.1.0/24, you could have this in
your tcpserver rules file:

192.168.1.:allow,RELAYCLIENT="",TCPREMOTEIP="",TCPREMOTEHOST=""

That would be right , i overlooked the obvious ....

Thanks ...

Although i have found scenarios where a patch rather then
TCP Server Rules would be better ...

Mainly where a Mail Server only allows Relay After SMTP-Auth
and the TCP Server Rule file only has Loopback and Default =)

Much Appreciated ....
