I'm hoping that this problem is not in the latest version of SpamFilter.

I'm seeing in .403 that SpamFilter is ignoring the sender email address domain and is validating host is ok to send in the host's domain.   That is only supposed to happen IF there is no sender email address available.   This is a bug in .403.

For example here's a spam I got from a bogus sender that SpamFilter incorrectly validated the host domain (interelate.net) for instead of the sender's domain (broderbund.com):

I didn't want to upgrade because we're not validating subdomains for SPF after .403, but .403 is ignoring sender email address domains for SPF.

Upgraded to .406 and the problem does not appear.  So, I've answered my own question.   Now I just have to suffer as the program treats host names as domains for SPF and MX queries
