I thought we already talked about this. :) Anyway go ahead an restrict the SMTP Virtual server on your Exchange 2000 box to only accept connections from the Imail server. This will not affect its ability to send mail in any way.
However if you have any users that use Outlook Express (or Outlook as a POP3/SMTP client), and they currently connect to the Exchange server to send mail, they will not be able to do so anymore. Unless you allow their IP addresses to connect as well. If they just use Outlook with MAPI or OWA, you don't need to do anything special. Another way would be to figure out why your firewall allows everyone to connect to your Exchange server's SMTP port. You should be able to define a rule on the firewall that would block everyone's inbound connections to the Exchange server on port 25 and only allow the Imail server to do that. -----Original Message----- From: Samantha Bridges [mailto:[EMAIL PROTECTED] Sent: Thursday, February 12, 2004 9:30 AM To: Exchange Discussions Subject: Inbound/Outbound Mail Question I have an Imail server on the outside of my firewall (PIX) and an Exchange 2000 server on the inside. I use an Imail server as a gateway virus/spam scanner. All mail comes through my Imail server where it is scanned for viruses and spam. From the Imail server, all mail is forwarded to mailboxes on Exchange. It works really good except that I am still receiving messages directly to the Exchange server mailbox, bypassing Imail. Basically, I want to only accept mail that comes from the Imail server. Should this be forced from the firewall or from Exchange? If I set inbound connections to only come from Imail what does that do to outgoing mail? What do I need to do to insure outbound delivery from Exchange...not out through Imail. In through Imail...through firewall.....to Exchange....Out through Firwall??? _________________________________________________________________ Get some great ideas here for your sweetheart on Valentine's Day - and beyond. http://special.msn.com/network/celebrateromance.armx _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Web Interface: http://intm-dl.sparklist.com/cgi-bin/lyris.pl?enter=exchange&text_mode=&lang =english To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] To unsubscribe via postal mail, please contact us at: Jupitermedia Corp.
