Title: Exim4 send/receives local and inter-organizational mail, but not to/from outside e-mails

Hi everyone,

We are running Debian 3.1 Sarge on a Dell PowerEdge 2800 server, and I was configuring Exim4 to send/receive e-mails.  It was the first going through the procedure, as we've always used Microsoft Exchange Server for our e-mails.

I chose "Mail sent by smarthost" option because the “Internet site” option sounds vulnerable to me.  For "IP-addresses to listen on for incoming SMTP connections”, I put my IP addr. and the loopback (127.0.0.1).  Finally, for the smarthost, I used one of the MS Exchange Servers.

During testing, I was able to send local mail, and mail to my Exchange Server account and vice versa.  However, I was neither able to send nor receive from outside e-mail addresses (hotmail, gmail, etc.).  So I was wondering what went wrong.  Are there conflicts of some sort with my configuration etc.?

Thanks in advance,
-Glen
