To configure sendmail, you must modify /etc/sendmail.cf 
- unfortunately, this file is almost "write only".

You can build "sendmail.cf" using the "m4" macro processor. Some
examples and a "README" can be found in the source tree of sendmail
starting at the "cf"-directory - e.g. /usr/src/sendmail-8.9.1a/cf/

Example (hides my private site name)

MASQUERADE_AS(my-isp.de)
MASQUERADE_DOMAIN(my-private-site.my-isp.de)
