OpenBSD 4.2 comes with Sendmail 8.14.1, with libmilter

How do i make sendmail use SPF querying to reject spam with spoofed
sender details? I want to be nice to everyone else and get rid of the
bounce messages going to the real domain of the fake sender spoofed in
the spam.

I saw a package p5-Mail-SPF-Query-1.999.1.tgz so i downloaded it to my
directory as per my PKG_PATH.

using pkg_add -nv i saw it had a few dependancies and I also
downloaded those to my PKG_PATH directory location.

If i run pkg_add to install this package now (and its dependancies)
what are the subsequent steps to make sendmai use SPF?

I notice a man page entry for spfd!!!! what is that? can sendmail use
that instead to perform SPF checks? The sendmail-milter-INSTALL.txt
file that comes with p5-Mail-SPF-Query-1.999.1.tgz only talks about
sendmail 8.12.x !!!

Anyone crossed this path on the 4.2 distro?

Regards

James

And I'll admit to replacing this with Postfix almost immediately.

It doesn't really answer your question, but Postfix makes testing and
rejecting spoofed emails very easy.

agreed.

sendmail is obsolete and needs to go away.
