Both - and the precise way you implement (or purchase) them.

It rather depends (unfortunately, for the non-techies amongst us). If you
run your own email server and pick mail up via HTTPS or, with a Blackberry,
you run your own Blackberry Enterprise Server (I don't know what happens
with the free "BES Express" package", your email is protected from snooping
over the mobile connection.
Obviously, if you use a service provider email account (including consumer
Blackberry packages) or a non-encrypted connection, then your mail can be
snooped by the provider (obviously) and, potentially, by people with radio
Of course, if the email comes to you clear-text, it can be snooped (the
non-triviality of fishing your particular email out of the millions not
withstanding) before it gets into your protected environment. There is a
general, albeit low-scale still, move towards encrypting mail server to mail
server comms (now using the STARTTLS SMTP extension, rather than GPG/PGPing
sensitive things up like the more paranoid of us have from some time.)
