Delivery has failed to these recipients or distribution lists:

UserMail@Domain.com
An error occurred while trying to deliver this message to the recipient's e-mail address. Microsoft Exchange will not try to redeliver this message for you. Please try resending this message, or provide the following diagnostic text to your system administrator.

The following organization rejected your message: Postini.

That's insufficient information to answer.

After the "this organization rejected your message" line, there should be "diagnostic information for administrators" IIRC.  That will tell you specifically why the message failed.

That being said, the two most common reasons IMHO are a user not existing and improper relay settings.

mahmoud.soliman@gbrands.com
Postini #550 No such user - psmtp ##

That's your problem.  According to the server that handles mail for gbrands.com, that user doesn't exist.

You said you have trouble sending to *some* outgoing addresses, right?  So your outbound email server seems to be set up correctly.

The real problem is, again, that the gbrands.com mail server -- which is the authority here -- says that the account mahmoud.soliman@gbrands.com doesn't exist.

It doesn't matter if you can send from it.  SMTP servers will take any properly constructed email address as a From: address.  That doesn't tell me the account is set up to receive email, or even that it actually exists.  That's how pranksters can spoof emails from president@whitehouse.gov if they want.

The mail server is clear in the error it returns when it says "no such user."  mahmoud.soliman@gbrands.com is not a valid recipient email.

And here is further proof.  This is from an email account of mine.

--------

This is an automatically generated Delivery Status Notification

Delivery to the following recipient failed permanently:

     mahmoud.soliman@gbrands.com

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 No such user - psmtp (state 14).
