The masquerading stuff works fine, but I'm trying to masquerade my laptop's
LookOut as MAILER_DAEMON so I can send insulting bounce messages to
spammers.

Ja, ja, and not to worry.  It's not exposed to the Internet, nor will it be.
No MX record, on a dial-up, behind a decent firewall, and it won't relay.
Although some of my questions here may indicate otherwise, I'm not a
complete maroon!

It's not my normal outgoing mailserver, so I don't think that will help.

I'll look, but the current .cf file was built by hand, not with M4 ....

I'm not using procmail, though, which is why I was hoping for a simple,
"couple-lines-in-sendmail.cf" solution.

I just want to drop all the X-headers from outgoing mail.

Thanks.
