You don't need a new condition to do this:
# message submission RCPT ACL:
require
verify = sender
set SENDER = ${sender_address_data}
# Check that authenticated users aren't pretending to be someone else.
deny
message = Sender address ${extract {user}{$SENDER} } \
does not match authenticated user $authenticated_id
authenticated = *
condition = ${extract {user}{$SENDER} \
{${if !eq{$value}{$authenticated_id} }} }
In the routers, we set the address data to contain various information
about the address. If it is eventually routed to a user's account, then
the address data includes a user=fanf2 clause which can be checked against
their authenticated ID as above.
