sneding Postfix to qmail unknown user error

[dexjul]

Hi,

I install postfix by defaut in our local server and if I send in our mail server (qmail) it bounce back <dexter.a@electronicscience.com>: unknown user: "dexter.a" , but this account is valid.

And I install postfix by default again in my pc via vmware machnie and I was received the email without any problem.

I dont know what is a problem our local server is same with my pc vmware configs.

Make sure that the MX record for your domain is pointing to the right server. Is there anything in the Postfix mail log when you send an email to that server?

How did you create the email account? What's in your main.cf?

You must set up an email account as follows: http://www.howtoforge.com/forums/showthread.php?t=2

Thank for your reply,

But I already an email account on the other server using qmail.

But if the account is on the other server, then you must modify the MX record so that it points to the other server.

This problem has been fixed.
