No, the result of the filter must be a valid SMTP command, not a postfix action. Have you tried setting main.cf "strict_rfc821_envelopes = no"? that might possibly avoid the problem. Otherwise, you'll need to use smtpd_command_filter to chop off the offending /wordpress part of the supplied address.
