I want sender address match my customer's domain name
If not match ,mean that sender address was fake
Hi Tom,
This is a bad idea, it is very easy for a spammer to spoof your
customer's sender domain in order to relay mail through your server and
then your server becomes not much better than an open relay.
You should look into SASL AUTH, this is a much better way for your
customers to authenticate to your server for relaying:
