Hi Joy, depending on what you want to achieve, you might want to have a look at http://www.milter.info/sendmail/milter-limit/ perhaps in combination with an outgoing-only instance of Postfix.

Kindly suggest me something so that i can have this feature implemented. I tried using smtpd_recipient_limit but unable to set per user restriction. Thanks Joy
