postfix+cyrus+procmail- master.cf setup

[Sandra]

What is the correct value of user in  from this line in master.cf ,
when I configure it to send messages to procmail?

I have copied this example from some archive message, but
every message goes to cyrus user. What could I put to it goes
to the correct user?

Thanks in advance :


procmail  unix  -       n       n       -       -       pipe flags=R
user=cyrus argv=/usr/local/bin/procmail -p /etc/procmailrc \
                 USER=${user} EXTENSION=${extension}
^^^^^^^^

^^^^^


Thanks a lot!
