If it's just for e-mail, a VPN may be a bit much. VPNs allow remote users
to connect to office LANs using an encrypted connection. Once they are
connected, everything is supposed to work as if their computer is located
inside the office.
The easiest way to secure the out-of-office e-mail is to use a mail server
that supports SSL. That would encrypt everything sent between users and the
server and is supported by the major e-mail programs.
We've got numerous ways to access our e-mail securely when away.
One way is to use Kerberos-based authentication and encryption. That works
reasonably well but is not supported properly by Outlook (Eudora works) and
thus needs a bit of additional software (not to mention quite a bit of
server infrastructure). There's also a slight problem when using Kerberos
from behind a router, which most people use at home.
The most common way is to connect to the SMTP/POP3/IMAP servers using SSL.
That's relatively straightforward but is limited to e-mail in that you have
to authenticate separately to each server (not an issue once Outlook is
configured). Most ISPs block the usual SMTP port (except to their own SMTP
server) but this is not the case for the default SSL SMTP port (and you can
move it).
Another option is to use VPN software, which makes it appear as if the
computer is located somewhere on the LAN. However, anything sent over the
LAN is no longer encrypted (that is probably not a major issue). There are
some routers available that will serve as a VPN endpoint (e.g.
ftp://ftp.linksys.com/pdf/wrv54g_ug.pdf).
