hahahahaha :-) I checked with my ISP. I asked why they didn't provide
instructions for people to use TLS with their server. They said that was
only available to corporate customers. I pointed out that they WERE
suppporting it - I only use encrypted mail connections - but that they
simply didn't provide the information to the users. They then modified
their configuration to use an improper security certificate at their end -
apparently they don't _want_ us using secure communications unless we pay
an extra fee to them. I stopped using them for mail...
