I'm running smail3.1 (patchlevel 16) on our >mail gateway. Smail doesn't remove information from messages. However, you can setup smail so that the workstations won't generate it (this may not work in patchlevel 16, though--please get a newer version). What I do at veritas is to transfer all mail internally as "local" mail. That is, the company-internal UUCP and SMTP mail transports all have the "local" flag set, thus transfering the message to the receiving site as if it came from a local user. When a message is sent out of the company, a different transport is used which does not have the "local" flag set, and which thus tacks on all of the domain information appropriate to the gateway. Doing this requires that local addresses be resolved consistently throughout the area where transfers are done with "local" set. Indeed, what I do here at veritas for the local user problem is to setup all machines other than the gateway to send mail to almost all users to the gateway (this can be done by dropping the user director from the directors file). Users can then setup whatever forwarding information they want on the gateway, using real-user addresses, which prevents automatic forwarding. -- tron |-<=>-| ARPAnet: veritas!tron@apple.com tron@veritas.com UUCPnet: {amdahl,apple,pyramid}!veritas!tron

Thanks to all who answered to my question about hiding machines in a LAN! [ the difference between usenet and rtfm is that you really GET answers that solve your problem from usenet people... :-) ] L.
