I have a recently installed BES and I am getting this sequence of error messages in the application log.
DoSMTPCommand: Expected 250 or 251, got 550
DoSMTPCommand: Command was: RCPT TO: <validuser@ourdomain.local>
DoSMTPCommand: Response was: 550 5.1.1 User unknown
SendMailMessage: Sent [RCPT TO: <validuser@ourdomain.local>]
SendMailMessage: Unable to find a valid SMTP host
Alarm::Email: SendMailMessage returned failure
I can't find anything in BB help/support. This is a single-user installation and the emails are being relayed okay, it seems, so what do these messages mean?
Can anyone help please?
Thanks
