I have Interworx set up with nodeworx users email to info@mydom.se - this emailaccount is on a windows-webbhosting server (same subnet as Interworx).
Problem is when Interworx sends an email to peterh@mydom.se it can’t be delivered:
Connected to 190.18.19.20 but sender was rejected.
Remote host said: 551 This mail server requires authentication before sending mail from a locally hosted domain. Please reconfigure your mail client to authenticate before sending mail.
So Interworx can’t send to peterh@mydom.se but to info@mydom.se??
I set up backup-jobs with email-notification to myself, that’s when I get this strange error.
