It is therefore still monolithic as far as Centos is concerned. postfix comes with mysql/postgresql support and with connection pooling at that and which can be used directly in a lot of built-in features of postfix. Unless the supporting stuff in the milters are as efficient as what you can get in postfix, sendmail + milters might be hard pressed to handle some environments that postfix can.
