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... :-)
