+==== Block sender based .qmail (Bouncesaying) ====
+Here is the quick work around to block sender / domain using .qmail for user OR domain.\\
+  * To disable "ketan@xyz.com" on domain "pqr.com" add code to file '.qmail-default'  under domain directory
+  * To disable "ketan@xyz.com" on "info@pqr.com" add code to file '.qmail-info' under domain directory.
+== To block sender : ==
+<code bash>
+| if [ "${SENDER}" = "ketan@xyz.com" ]; then /var/qmail/bin/bouncesaying 'RESTRICTED: Domain policy disallows sending email to our domain.'; fi;
+</code>
+== To block Domain : ==
+Blocking xyz.com to send email to ketan@pqr.com
+<code bash>
+| /var/qmail/bin/bouncesaying 'RESTRICTED: Domain policy disallows sending email to our domain.' sh -c 'echo $SENDER | grep -qi "@xyz.com$"'
+</code>
+== To forward if outgoing match ==
+<code bash>
+|if [ "$SENDER" = "support@test.k2patel.in" ]; then /var/qmail/bin/forward fire@power.com; fi
