Hi Jeff
I am wrestling with the same problem. However I set the masquerading - it just wont do it. My theory is that the user "root" is a "trusted user" and is allowed to override outgoing email addresses. I think this is overriding the masquerading. I suspect that the masquerading will work for non-trusted users. Also - if I change roots "from addresss" to eliminate the "host" then both the from " and "envelope sender" are sent without the host. Let me know if you find a better solution.

Since you are using NAT, the important IP address and host nameassociated with it is the one the outside world sees. Does that IP address have a host name the world sees and does that name then resolve to the same IP address?
Yup -- that's what I'm trying to get sendmail to use, but it's insisting on using the internal hostname, inclusive of the machine name. I.e., "betsy.example.com" is the actual hostname, at 10.x.x.x; all the 10.x.x.x machines have custom /etc/hosts that define betsy.example.com, etc., with their 10.x.x.x IPs. When it sends email to the outside world, I need to to send as "example.com", dropping the "betsy" part.
Is this really that hard?
