Open-Relay

I would like to create the following ideal situation,
but I'm not sure what the best solution is, or if there
is one at all.

I would like to allow my clients to be given a pop/smtp/imap
account and be able to get and send email using a variety
of mailers and web-based access, however, I don't want to be
an open-relay.

So, that leaves several questions.

Is there an encrypted method to log into pop, smtp, and
imap so that villians with packet sniffers can't
borrow legitimate users passwords? Can mail software
use them?

What solutions are there for those who want to provide
easy flexible email solutions to clients but don't want
to behave badly on the internet.

I understand the need to provide the restrictions against
being an open relay, but I would like to be able to provide
users email accounts that they can access and use using
some set of MTA's on different OS's to send and receive mail.

Is there a way to provide varying levels of service to
people in different levels of trust, giving highest
flexibility and access to the most trusted and restricted
access to the general public.

Is there solutions postfix website for us folks who would be
perfectly happy to provide free service to the world
if it weren't for the spammers who've spoiled it for
us all.
