Vaugh,
Are you currently using a VPN setup? We are testing using SafeNet SoftPK
and a Cisco router. Point to Point from a static IP works beautifully.
Getting it to work from DHCP dial-ups using certificates for authentication
has been a nightmare. If you have something in place that works from a
DHCP dial-up account please let me know... At this point I am probably going
to go looking for a different vendor.

Allowing POP3, IMAP4, and HTTP access to your IMAIL system will cause
passwords to be sent over the internet in clear text. If these are mail
only passwords then your risk is limited, but if they are "universal"
passwords then potential security risks go up exponentially. One way around
that is VPN (Virtual Private Networking) so that the connection is secured
before you even send the password. This can be accomplished by placing VPN
software on your router, and remote client stations that will access your
servers across the internet. The router encrypts all outbound packets and
the workstation decrypts them, responses from the remote workstation are
encrypted and then decrypted by your router so IMAIL does not need to be VPN
aware. This suggestions does come with some costs and maintenance, but
allows you to extend the walls of your security policy to wrap around and
include your remote users.
Short answer:
POP3, IMAP, and IMAIL's HTTP are authenticated services and passwords are
"sniffable" in transit.
