When using Mozilla Thunderbird - when I try to send out Emails the following occurs;

"ALERT"

An error occurred sending mail. The mail server sent an incorrect greeting: 5.7.1 < unknown [14.137.73.189] > client host rejected: Access denied.

Why I have been able to send Emails to specific Email addresses - but now, for some reason I do not understand - I cannot.

How do I fix this problem?

What is your SMTP server? What is the domain part of your email address or your email provider? What is your ISP?
