RE: Message headers expose local net
Followed FAQ 5.5 explicitly. It made no changes to the header addresses - it did create delivery failures. If there were other dependencies needed other than section 5.5 the FAQ did not mention them. I would assume this is straightforward issue. I doubt that millions are spent on firewalls to protect information about your internal network - just to advertise the host names and addresses in the email headers. Any pointers appreciated. d. divine > Messages sent from the local network show the host's IP address and name in > the header.

To really clean up, see FAQ 5.5 and filter the message through formail (from procmail) or reformail (http://i.am/mrsam) before qmail-inject. Both will let you delete certain headers or let ony certain headers go through, AFAIK. Stefan

You can manually set TCPREMOTEIP and TCPREMOTEHOST in qmail-smtpd's environment for connections from your local network. If you're using tcpserver, you can set up something like the following in your rules file (assuming your local network is 192.168.1.*): 192.168.1.:allow,TCPREMOTEIP="unknown",TCPREMOTEHOST="unknown",RELAYCLIENT="" That's untested, but I don't see any reason why it wouldn't work (and if it won't, I'm sure someone will be quick to point out why).

Message headers expose local net
Messages sent from the local network show the host's IP address and name in the header. What setting will prevent internal network information being sent over the internet (sending only the qmail host name, address and sender@domain.). thank you.
