550 Authentication turned on in your email client

[Sunny55]

Whenever i try to send an email from my system, i get the following error message "550 Authentication turned on in your email client" on my desktop screen. Can any body tell me that why i'm not able to send any email from my pc? Does any body knows about it? Kindly provide me the correct solution in order to get rid of the above issue.

It seems to be that you are trying to use your server in order to send mail from your remote location. For that you need to turn on SMTP authentification on your Outlook email client.

It seems to be that you trying to enter the wrong password for your email addresses. Try to enter the correct password for your email addresses or try to recheck your passwords.

According to my best of knowledge it seems to be a DNS issue on your system. It might be possible that your mail client is having the SSL authentication enabled and you need to disable it, on the options section of your particular program running on your system.
