The file that is being modified by the iTools7 interface is:

This is correct. MailServer/Configuration/local-host-names is blank, the files in that directory

are not used except sendmail.cf. This is because /Library is a group writable directory and

Sendmail can not use configuration files that is located in a group writable directory.

Therefore, the configuration files in Mail/Configuration are served as template files only in

the initial install.

The way I understood relay domains to work for our situation is that you put

the IP address of the LAN router that supports our office network into the

relay-domains file and then sendmail will allow clients that are behind that

router to use sendmail to send and receive email.

I assume you are using the iTools system as mail.dbmscan.com right?

I did a nslookup and I found:

mail.dbmscan.com

Server: apollo.1.168.192.in-addr.arpa

Address: 192.168.1.100

Non-authoritative answer:

mail.dbmscan.com canonical name = www.dbmscan.com

The mail.dbmscan.com is a CNAME record to www.dbmscan.com. You should

change that to A record. Then Sendmail will function properly.

Sendmail does not work when mail exchanger address is a CNAME record.

Hope this helps.
