If this is Redhat/clone, it's because /usr/lib/sendmail ends up being  
pointed to sendmail.

$ ls -al /usr/lib/sendmail
lrwxrwxrwx 1 root root 30 Nov  7  2008 /usr/lib/sendmail -> /etc/ 
alternatives/mta-sendmail

$ ls -l /etc/alternatives/mta-sendmail
lrwxrwxrwx 1 root root 26 Nov  7  2008 /etc/alternatives/mta-sendmail - 
 > /usr/lib/sendmail.sendmail

$ ls -l /usr/lib/sendmail*
lrwxrwxrwx 1 root root 30 Nov  7  2008 /usr/lib/sendmail -> /etc/ 
alternatives/mta-sendmail
lrwxrwxrwx 1 root root 24 Nov  7  2008 /usr/lib/sendmail.postfix -> ../ 
sbin/sendmail.postfix
lrwxrwxrwx 1 root root 16 Nov  7  2008 /usr/lib/sendmail.sendmail - 
 > ../sbin/sendmail

You can use the 'alternatives' command to view and change this  
configuration --

# alternatives --display mta
mta - status is auto.
  link currently points to /usr/sbin/sendmail.sendmail
/usr/sbin/sendmail.sendmail - priority 90
  slave mta-pam: /etc/pam.d/smtp.sendmail
  slave mta-mailq: /usr/bin/mailq.sendmail
  slave mta-newaliases: /usr/bin/newaliases.sendmail
  slave mta-rmail: /usr/bin/rmail.sendmail
  slave mta-sendmail: /usr/lib/sendmail.sendmail
  slave mta-mailqman: /usr/share/man/man1/mailq.sendmail.1.gz
  slave mta-newaliasesman: /usr/share/man/man1/newaliases.sendmail.1.gz
  slave mta-aliasesman: /usr/share/man/man5/aliases.sendmail.5.gz
  slave mta-sendmailman: /usr/share/man/man8/sendmail.sendmail.8.gz
/usr/sbin/sendmail.postfix - priority 30
  slave mta-pam: /etc/pam.d/smtp.postfix
  slave mta-mailq: /usr/bin/mailq.postfix
  slave mta-newaliases: /usr/bin/newaliases.postfix
  slave mta-rmail: /usr/bin/rmail.postfix
  slave mta-sendmail: /usr/lib/sendmail.postfix
  slave mta-mailqman: /usr/share/man/man1/mailq.postfix.1.gz
  slave mta-newaliasesman: /usr/share/man/man1/newaliases.postfix.1.gz
  slave mta-aliasesman: /usr/share/man/man5/aliases.postfix.5.gz
  slave mta-sendmailman: /usr/share/man/man1/sendmail.postfix.1.gz
Current `best' version is /usr/sbin/sendmail.sendmail.

I believe that all you need to do is run 'alternatives --config mta'  
and choose postfix but I haven't researched this extensively.
