yea, it would only accept normal passwords, but I figured since it
was using tls/ssl that the whole shebang was encypted anyway so
it should be fine, right?


Also, still getting spam of course, nut a smidgeon compared to before.
I would say 99.9% is being tagged by spam assassin as [spam].
Still afraid of false positives so gonna watch for a while with spamassassin
before I dev null them buggers.
