DB mail fails with permission error

Hi:

I am trying to send mail using DB Mail. I made sure that there is a mail box setup for the service account and the service broker is enabled in the msdb database. Also I made the service account a user in the msdb and added him to the mail role as specified in BOL. However I consistently end up with the following error message when I try to send the mail.

Log ID 19
Process ID 5672
Mail Item ID 6

Message
The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 1 (2006-04-26T11:05:00). Exception Message: Cannot send mails to mail server. (Client does not have permission to submit mail to this server. The server response was: 5.7.3 Client does not have permission to Send As this sender.).
)

I am at loss to understand what Permissions it still needs?. Any thoughts appreciated.

Thanks

I have resolved this problem successfully and want to share it with the community for the benefit of others.

when the above error happens, please make sure that you have the following in place.

1). The Service account should have a mail box setup.

2). The account name you use when you configure DB Mail should be the same as that of the Mail box name.

3). The Account should be a user in the msdb and should be added to the DBMailuser role.

Everything then should work fine.

Thanks
