Cannot send emails "An error occurred while sending mail: The mail server sent an incorrect greeting: Administrative prohibition."
I have started to been unable to send emails, I get this error message come up "An error occurred while sending mail: The mail server sent an incorrect greeting: Administrative prohibition."
I have not changed any of my email settings.
Does anyone know why this would be happening?
Thank you for your help in advance.

Possible rejection due to a server spam filter, maybe your email address or your IP address or the sending server IP address. See if this has anything to do with your IP address or email address.
