The first thing to do is some debugging: in the popbsmtp.sh
script write the received parameters to a file, and decide where
the problem is!  For exemple,

	echo "Login from $3, parameters 1=$1, 2=$2, 3=$3, 4=$4" >> /var/log/dovecot3

I did not need to put %r in the dovecot.conf, my line is

	mail_executable = /usr/lib/dovecot/popbsmtp.sh /usr/lib/dovecot/pop3

If you put any junk afterwards, you will find that it's not $3
anymore but $4 or $5 or whatever.

My dovecot version is a 1.0stable.
