I'm having some trouble getting sendmail masquerading to work.

I've got a Linux box connected to an ISP using dynamically-allocated
IP numbers. With pppd this seems to work very well. Incoming email
gets downloaded with popclient; outgoing is sent with sendmail.

The problem: My ISP is rmi.net; my Linux box is named 'harry'. All

is not a valid domain, nor is it likely to become one. Outgoing
email really needs to be from rmi.net.

I thought I had this solved when I read about sendmail masquerading.
I created an m4 file with the following entries:

MASQUERADE_AS(rmi.net)
FEATURE(masquerade_envelope)

...and created a new config file. But outgoing email still claims
to be from harry.rmi.net.

I get the feeling I've missed some obvious detail here. Can this
be done with sendmail? And if not, what should I be using for
outgoing email?

With sendmail nothing is obvious. What you want to do can
be done--you can even masquerade the domain of recipients. Here
is the start of my 4m config, if it helps. Order _IS_ important,
as I have discovered to my immense frustration.
This masquerades the internal 'home' network as 'outside.com'
masquerade_envelope should be what you want. masquerade_all
may be more than you want.
