Thirdly ... I think it's ridiculous that Stanford's anti-spam rules
trawl through Received headers (which are defined as being free-form)
and look for suspicious hostnames when you've already sent that email
through your email provider and it has a valid DKIM header; gmail has
already certified that the email came from an authenticated user, why
does Stanford care what your local hostname is?
I too initially thought that their anti-spam rules were a bit draconian
to care whether the HELO host is localhost.localdomain or any other user
provided piece of information, however, after some reflection, I
realized that they may have a bayesian filter that has automatically
assigned a 99% spam probability to the word ``localhost.localdomain''
based on the statistical influence of past spam messages containing it.
Of course, I'm giving them the benefit of the doubt of having such an
intelligently designed anti-spam mechanism... :-)
