Hi all -
Here's my problem - EarthLink has been unreliable as an email SMTP relay service so I need to configure my Exchange server to take over those responsibilities. (We have configured our traveling exec's outlook to use smtpauth.earhlink.net for the outgoing mail server and now need to change that to an internal one) For the most part it looks pretty easy (and that's what worries me). I know that if you leave the relay open, your server can be used as by spammers and we can't have our site blacklisted. So does anybody out there know some good references for setting this up or have some advice having done it them selves?
I've been reading in the Learning Exchange Server 2003 book by Boswell and have read in the Exchange Server 2003 Administrators Pocket reference but I still get the feeling I'm missing something.
What I have so far is that you need to set up an SMTP connector designating the server as a bridgehead (we only have 1 Exchange Server) Allowing the server to deliver directly to the target host. The problem I see with this is allowing SMTP traffic through the firewall to the Exchange server.
The other option is to set up a Smart Host - the only server I have that might work for this is our web server - just don't know if it will work there ok.
Both our Exchange server and our web server run Antivirus software, in addition the Exchange server runs Scan mail to check the messages.
So which option is better and why? (I am still new to some of this and I really get a little paranoid when it comes to making major system changes).
Or does anybody know of some white papers out there will help me to make a good decision.
If more information is needed, please let me know.
I appreciate the assistance.
