For the past 2 days I have been unable to send emails to anyone in my address book, I am still able to receive emails. I have not installed any new software/hardware.... The full error message I am recieving is below:
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was '[email protected]'. Subject 'Hey', Account: 'mail.stis.net', Server: 'mail.stis.net', Protocol: SMTP, Server Response: '554 <01-186.189.popsite.net[66.217.65.186]>: Client host rejected: Access denied', Port: 25, Secure(SSL): No, Server Error: 554, Error Number: 0x800CCC79
I tried to ping both 01.186.189 and 66.217.65.186 and both came back with request time outs....
any suggestions would be appreciated....
Thanks
