When an outgoing email's target address is prefixed by '+', I would
like postfix to delete it replying back to the client ok status.

I had previously setup below.  But this sends back to the client 554.
I would like the client to think that in this situation everything is
fine.

main.cf

smtpd_recipient_restrictions =
            check_recipient_access pcre:/etc/postfix/recipient_access.pcre
            reject


recipient_access.pcre

/\+(,*)/        reject
/(,*)/          permit
