They need to sync to their mailbox for when they are on the road. I might have to use pop or trying imap now. Or might have to use VPN.

There was just a VERY long discussion in the MS Security Focus mailing list because someone wanted to open ports to allow an Outlook client to directly attach to an Exchange server from the Internet. Some said to use ISA server, while others (like me) said to use a VPN device. You NEVER want to open RPC to the Internet. You are just begging hackers to break into your system and get critical information. Again, my question goes back to "why are you wanting to open ports for your Exchange server to the Internet?" Is it because someone wants to get to their mailbox? If so, then either publish Outlook, or have them connect to OWA (secured with an SSL certificate).

I would suggest maybe just POP the box, unless you want the Exchange Address Book/Public Folders/etc. Or better yet, implement a published application via Citrix and create a connection that way. ;-) Personally, I am not in favor of opening any more ports than absolutely necessary. - -----Original Message----- From: Chris Lynch [mailto:lynch00@xxxxxxx]=3D3D20 Sent: Wednesday, March 12, 2003 4:48 PM To: thin@xxxxxxxxxxxxx Subject: [THIN] Re: OT: Access Exchange from outside firewall =3D3D3D20 - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Why are you doing this?
