Authentication Denied (VM320), Authentication Denied (VM321),
The explanations for those two error codes are:
- VM320 error code means too many successful authentications using your email account credentials have been made to the VM SMTP email server within an hour.
- VM321 error code means too many unsuccessful authentications using your email account credentials have been made to the VM SMTP email server within an hour.
In both cases they result in the VM SMTP server blocking access to your account so your email apps are unable to send emails from your VM email account. However, VM webmail works in a different way and so will be unaffected by those errors.
I would suggest not attempting to send or receive emails from the apps for at least an hour, but the longer the better . Then try running the Curl command again and see if it still reports a VM320 or VM321 error. (That will be towards the very end of the resulting output.)
If it does, or if the problem comes up repeatedly, you need to investigate why the VM email server is receiving such an unusually large number of authentication attempts with your VM email address and a valid password.
It could be that a smart device on your network has been infected with malware and is attempting to send spam emails. Or it could be that your email credentials are being used by a spammer .
Either way, it would be worth changing your VM password and mail app password.
