BTW, if you have Exchange 2003, Windows 2003 web server, and your clients
use Outlook 2003, you can use RPC over HTTP for full Outlook functionality.
For more information, read the following:

I suggest you use IMAP4 instead of POP3.  Inbox caching is enabled by
default in Outlook Express 6 for IMAP4.  So, your clients can use their
inbox just like using Outlook.  IMAP4 also supports default public folder
tree.  However, IMAP4 don't support calendar, mailbox contact list, tasks,
... etc.   To Access the calendar, your clients still need use OWA.
For informaton about how to setup IMAP4:

For SMTP, if your clients don't need secure channel, you can ask your
clients to use the SMTP server provided by their local ISP.  If all client
messages must be encrypted and route through your company's SMTP, you need
to configure an SSL enabled SMTP virtual server that require authentication.
FYI, you should use port 25 for your SSL/TLS SMTP virtual server, OE6 and
Outlook only support STARTTLS type SSL SMTP (RFC 2487) on port 25.  You can
configure OE6 and Outlook to use other port with SSL, but that doesn't work
if your SMTP is IIS or Exchange Server.   If you only have one public IP
available to use as SMTP, you can use the follow setting:
To temperorily solve the problem, I setup a single virtual server using the
TCP 25 port.  It allows either anomynous non-SSL connection or
Basic-Authentication TLS connection.  Anomynous asscess and basic
authentication requiring TLS is checked, NT authentication is disabled as it
doesn't require encryption.  Web server certificate is installed on the
virtual server but security channel is not required.  Relay is only allowed
for authenticated users.  The result: incomming and outgoing SMTP messages
can route through the virtual server without authentication, but public
relay is not allowed; client submission must be authenticated/encrypted
using TLS and can be relay out of the organization.
