hi i have database mail set up in my server with the same smtp configurations i have in other servers which are working fine. But with this server i keep getting this error:
The mail could not be sent to the recipients because of the mail server failure. (Sending Mail using Account 1 (2010-10-14T14:01:11). Exception Message: Cannot send mails to mail server. (Mailbox unavailable. The server response was: 5.7.1 Client does not have permissions to send as this sender).
)
can you tell me what else to check please

that your email server is allowing this particular SQL Server to relay.
That the user account that is the 'sender' from SQL server is a good address. (if it is authenticating)

what would be the user account that is the 'sender' ? the sql server agent login account? does it need a role?

unless you have chosen to use SMTP authentication, it can be anything you want.
so , if you authenticate, it has to be a real email address on the email server.
if you send with no authentication, it can be whatever.

issue fixed , i needed to add the ip address to the relay.

I know this is a really old post but i resolved this issue by creating an Operator as i was trying to send emails without first creating an operator and hence the error message was saying unavailable mailbox
Good luck
