Hi all,
Is it possible in Postfix to allow just relaying one mail (independent
of the number of rcpt) per sasl login?. I perhaps could interested on

HI All
Postfix will try to deliver email based on A record suppose the mx record is

I mean to say postfix should send email based on MX record only and if mx
record not bound then immediatly bounce the sender .
