others doing something stupid is not a good argument

you realize that this is only possible if the RCPT is on
your own server and not remote mails?

which should be enough for argumentation why such things are
making more damage as they solve problems and they are only
working for non-relay mails

surely YOU can win, you must learn to sell quality and explain
why you are not doing anything someone wishes if you are sure
that it is a bd idea

why would i want a customer which enforces me to impelement a solution
where i am sure that it is stupid - if he does not understand my
argumentation he better is not my customer
