Interesting. According to the RELEASE_NOTES, that was added in 8.7. Strange that I missed that.... > One > could set that to a blank on all machines on the "inside" of the > firewall? But then, if you had mail problems inside the firewall, a very important diagnostic tool would be taken away from you. Moreover, if you had a loop (user A forwards all mail to user B who forwards all mail to user C who forwards all mail back to user A), by defining this header to be null, you would never break the mail loop and you would probably kill the mail system on a fairly regular basis. The more stuff you have behind the firewall (and the more users), the more likely that this will be a problem, and the more frequent this problem will be. -- Brad Knowles, <brad.knowles@skynet.be> "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety." -Benjamin Franklin, Historical Review of Pennsylvania.
