We are having an issue with XTRF.
The automatic messages (such as POs, invoices, etc.) are not being sent automatically by the system.
This problem appeared yesterday.
Could not even report the issue via XTRF homepage, it shows an error
E-mail could not be sent, reason: 535 5.7.8 Error: authentication failed: authentication failure
Tried contacting people via e-mail, but as you can see with little success.
