I know quite a few of you have had this problem, so I thought I’d show you how to fix this. This applies for both exchange 2007 and 2010.
You need to allow exchange to accept incoming SMTP from non-authenticated applications – in our case BackupExec
Head over to your Exchange Console, into your sever configuration > hub transport > you should see receive connectors. Go and ahead and create a new connector. You want a custom connector. Call it something sensible (BackupExec and the name of the server).
I don’t like to keep stuff on standard ports, it’s just me – so I always change this to port 26 – after this click next.
Now delete this crappy default and click the add arrow drop down to add a single IP (this the IP address of the BackupExec server – this can be the server you working on if it’s SBS)
Go ahead and finish creating this. Once done, right and click and head into the properties of the connector.
Click the permission tab and allow exchange servers.
Apply and head into the Authentication tab and click the box ‘Externally Secured’ – nothing else in here should be ticked!!
Now ahead back over to BackupExec. Tools > Email and Pager notifications. This should all make sense now. SMTP mail server is your exchange / sbs server name. And the account your using to send the mail.
Any questions, feel free to comment.
