I don't know what version of sendmail you use with Sidewinder, but under V8.9 you we use: FEATURE(always_add_domain)dnl FEATURE(masquerade_entire_domain)dnl FEATURE(masquerade_envelope)dnl MASQUERADE_AS(`enteka.com')dnl I think the trick is that you need the masquerade_envelope. If you are trying to remove it from fields like "msgid" as well, it is a little messier. You'll need to change the format of these fields (and a few others) like: ?M?HMessage-ID: <$t.$i.$m> (you'll also want to change Resent-Message-ID and anything else that normally uses $j [full host name]) To strip out Message-ID's that you receive, well, that's a tricky one that most likely will need some modifications to the Sendmail source code. In general, I don't believe messing with the headers is worth it. You gain very little in security, but you have a huge problem if you need to track down mail problems.

I'm running a sidewinder Firewall with version 3.2 of the software. I am
trying
to hide or remove internal host information from my e-mail message headers.
If
you look at the headers for this e-mail, you will see my internal mail server's name and ip address. I have tried using: MASQUERADE_AS(domain.com)dnl MASQUERADE_DOMAIN(domain.com)dnl FEATURE(masquerade_entire_domain)dnl replacing domain.com with the domain information I want. None of this
worked.
I called Secure Computing, and I haven't gotten the information they promised me. Does anyone have any ideas on how to mask this sensitive information. Richard Christie
