Hi There,

I am using Postfix as my mail server. I do not know why i can send out an email to all the domain but i cannot receive email from some of the domain.


i can send email to both abc@yahoo.com & bcd@abccompany.com . But when abc@yahoo.com reply the email, i CAN receive the email. And, when bcd@abccompany.com reply the email, i CANNOT receive the email.

Anybody can tell me what happen to my main.cf configuration.

Hope someone can help me. Thanks.
