Making sendmail only accept mail to genuine Exchange users

[Idan Plotnik]

Hi Stephen,

Thanks for your answer.
I will upgrade it soon.
I have some questions about this methodology if you don’t mind:
1. in this phase i don’t want to use the VBscript so I create and copy the 
   file " whitelist-addresses.txt" manually to the /etc/mail directory.
2. I don’t understend what this line means in the perl script:
   my $exchangebox="exchange.yourdomain.com";
   I saw that when I run the script he create the files mailhost and 
   mailhost.db that contain the mail address from the whitelist-addresses 
   file and add the value that he has in the $exchangebox variable, why ???
   How the MailScanner know to translate the DNS name to the IP address ?
   And If I put there IP Address its not working.
3. why I need to put the Exchnage IP address inside the "access" file ? the 
   access file contain the domain name that the Sendmail will authorize 
   RELAY to.
   I don’t send my emails through the MailScanner, just incoming emails.
4. why I need to delete all the entries in the mailertable file ?
   How the sendmail will know to send the emails to the Exchnage server ?
   In the mailertable I configure "domain_name   ip_addr_exchnage"

Thanks a lot.

We've installed this methodology at many client sites and it works quit
well.

Why would you want to install a fairly old version of MailScanner?
