Ill throw in .02 Assuming you are referring to allowing remote users to get their e-mail.
I'm doing the OWA thing for "remote/roaming" users. I do some Citrix for full desktops. I do NOT allow users to connect to the exch box at this time via SMTP/POP. I do at this time use the Simple Webshield product bundled with the NIA/Mcafee TVD suite. It does reside on it's own machine. so Internet smtp > webshield > Exch. yes the webshield sit's before Exch box. Yes it provides me with an additional layer of pre exch virus protection...works ok yes it also provides some prefiltering on attachments...sucks...does not go any deeper the first level i.e. FWD> FWD it will miss. Note: Their full blown product webshield APP is supposed to work well..no exp with it, Ill keep my opinions to myself.. If I had to let user(s) directly get to either port 110/POP and port25/smtp to do their e-mail... 1.) I would not ..thats me.. 2.) Forced too only via some secure connection like a VPN. bill PS for those interested I run the AV product to at the file level and scan all files on the exchange box with no exceptions. ;-) -----Original Message----- From: Bendall, Paul [mailto:[EMAIL PROTECTED]] Sent: Thursday, June 06, 2002 1:38 PM To: Exchange Discussions Subject: RE: lesser of the evils - ssl or smtp Okay I'll add another spanner to your works, I would advise an SMTP relay server on your DMZ but I really wouldn't use McAfee Webshield. Why I hear you cry for one it is pretty bad at blocking viruses and two we have had no end of problems with it crashing or not sending to certain domains when it gets a DAT update. Why not use the SMTP component of IIS as your SMTP relay server and then use ScanMail or Antigen on your Exchange server. Either that or use someone like MessageLabs to outsource your antivirus too.

Exchange 2000 mailbox server on the LAN, accepting/making connections using SMTP through a firewall to the internet Exchange 2000 mailbox server on the LAN, accepting SSL secured OWA connections from the internet, again, protected by a firewall. Basically I am being told I may have to do both with the same box, but I'd rather have the smtp traffic going through a DMZ based gateway running McAfee Webshield, and let the OWA clients come into the internal box over SSL (which I see as less of a risk than opening up port 25. If you had to choose one of the 2 above scenarios, which would it be?
