An error occurred while sending mail: The mail server sent an incorrect greeting: Cannot connect to SMTP server 69.168.106.129 (69.168.106.129:25), connect error 10060.

I have recently moved and am now with Suddenlink. I had no problems for the first week and a half. The last couple of days I am unable to send emails.
