Postfix - matching an envelope attribute

[f***@gmail.com]

Hi everyone, I'm using postfix as a relay for multiple email servers.
I can't figure out if postfix can match an envelope attribute then execute an action(DISCARD, HOLD, WARN,...), like it does with header and body lines.
Does anyone knows if that is possible ?
