There are several good reasons for a configuration like this.
It looks like the '12.14.x.y' server (an Internet address) is acting as a
buffer for the local network mail server. If '12.14.x.y' is
compromised/crashes, local mail is unaffected. Also makes the sendmail
configuration a little easier for to handle. You may want different rules
for the internal sendmail and the external sendmail. (Assuming that's the
SMTP MTA in question)
