I suggest you ditch the POP and host your mail on the server directly. Then
the remote users can use OWA or POP from your server itself.
See
http://www.swinc.com/resource/exch_smtp_diatribe.htm
For Exchange 2000, see
http://www.msexchange.org/tutorials/MF002.html for
instructions on how to get Exchange to receive Internet mail sent via SMTP,
the way it's meant to do - for Exchange 5.5, see
http://www.exchangeadmin.com/Articles/Index.cfm?ArticleID=15729
You can do this even with dialup/ISDN (get an ISP who supports ETRN) .
If you have broadband but with a dynamic IP (such as a cable modem/ADSL
account):
You can use a dynamic DNS host such as www.dyndns.org - you set up an
account, such as yourcompany.dnsalias.com, and whomever hosts your public
DNS should set your primary MX record to point to yourcompany.dnsalias.com.
Open up port 25 inbound in your firewall or router, direct all traffic to
your internal IP for the Exchange server.
You run a service on your server (software available for download from the
dyndns website) and set it up to update dyndns with your current dynamic
IP.
