This uses the same mail delivery process multiple times.

> **OR** use /usr/cyrus/bin/deliver as follows:

> cyrus     unix  -       n       n       -       -       pipe

> ${extension} ${user}
> in /etc/postfix/main.cf:
> mailbox_transport = cyrus

This executes the /usr/cyrus/bin/deliver file once for every mail
delivery.
