hi,

 Error = 5.7.1

You are trying to relay your mail through another SMTP server, and the server does not permit you to relay.

The recipient may have mailbox delivery restrictions enabled. For example, if a recipient’s mailbox delivery restriction is set to receive mail from a distribution list only, non-member’s mail will be rejected and produce this error.

General access denied, sender access denied—the sender of the message does not have the required permissions necessary to complete delivery.


Check system privileges and attributes for the contact, and try sending the message again. Also, to resolve other potential issues, ensure that you are running Exchange 2000 SP1or later. check the SMTP server's relay restrictions.

hope this may solve your problem

It's more likely the default relay restrictions weren't changed than an inadvertant Smart Host was inserted.... IMHO
