Alert -An error occurred sending mail - The mail server sent an incorrect greeting: 5.7.1 < unknown - waht does this mean?
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?
