Problem sending email from desktop
Since yesterday, I've been unable to send email from my desktop client. (I'm on a Mac.) I can send email from my phone and from webmail.
The message I receive says:
"The sender address [my email] was rejected by the server smtp.ntlworld.com.
The server response was: Authentication Required (VM401)
Select a different outgoing mail server from the list below or click Try Later to leave the message in your Outbox until it can be sent."
I contacted the WhatsApp support. They recommended first that I change my password, which I did, and then that I press the pinhole reset button on Hub 3.0. I did both of these things and neither worked.
There doesn't seem to be any other way of getting help from Virgin Media apart from posting here.
Any suggestions? I *think* that possibly what is happening is that the server is rejecting my messages because it thinks they're spam (the other day I had a bunch of non-deliveries from what was clearly spam someone had sent using my account) but I can't be sure. It doesn't explain why it works OK from webmail and my phone.
Thanks in advance for any help.
