Hi, helping a user with his email account (gmail account). when anyone tries to send to his email account they will get a kickback message. He can send out but no one in.
Here is kickback message:

Hi. This is the qmail-send program at oproxy1-pub.bluehost.com.
I'm afraid I wasn't able to deliver your message to the following addresses.
This is a permanent error; I've given up. Sorry it didn't work out.

<brad@pinstrat.com>: does not like recipient.

Seems the net thinks it is your MX records.

Here is one of the results I get when I google the error


PS: I fixed your title

@glamo ,

I beleive you are sending the email to brad@pinstrat.com. This domain "pinstrat.com" has two MX records.

0       smtp.secureserver.net
10       mailstore1.secureserver.net

Ideally you should be sending the email to "smtp.secureserver.net" ( and NOT to "mailstore1.secureserver.net" (

Since "smtp.secureserver.net" ( and MX priority 0 mails should be sent to it only, the other server might be for diaster recovery or might in some cases might not accept the emails unless "smtp.secureserver.net" ( goes down.

Further even if "smtp.secureserver.net" ( rejects the email then you may need to contact the IT support of the recipient or domain master of "pinstrat.com" and asked them that their mail server is not accpeting the email for the domain pinstrat.com.

@glamo, how is the problem connected to gmail?
Experts Exchange is like having an extremely knowledgeable team sitting and waiting for your call. Couldn't do my job half as well as I do without it!
