expansion in master.cf

Hello,

Is anyone familiar with how ${recipient} gets expanded when passed in the postfix master.cf file to a external mail filter?

The man page for "pipe" says:
"A command-line argument that contains ${recipient} expands to as many command-line arguments as there are recipients.",

so I'd expect multiple recipients in the command line if there are multiple addresses in, say, the "To:" field.

Though I appear to actually get multiple invocations of the filter, with one recipient each time...any ideas on what the expected behavior is?

filter unix - n n - - pipe
flags=Rq user=filter argv=/usr/bin/procmail -Y -m /etc/procmail/mainfilter.rc ${sender} ${recipient}

Cheers
mvm
