Problems with sending emails in Outlook express
Posted on 2005-05-06
I get the following error when i try and send a message
The message could not be sent because one of the recipients was rejected by the server. The rejected e-mail address was 'email@example.com'. Subject 'Test', Account: 'ilopia.com', Server: 'ilopia.com', Protocol: SMTP, Server Response: '550 5.7.1 Unable to relay for firstname.lastname@example.org', Port: 25, Secure(SSL): No, Server Error: 550, Error Number: 0x800CCC79
I am running Server 2003, I have a Mail server(pop3, SMPT) configured. I am not behind a firewall, I DO HAVE "MY SERVER REQUIRES AUTHENTICATION" CHECKED.
My Domain: mydomain.com
I can send emails to my own account(localy, email@example.com), I cant send emails to other accounts(firstname.lastname@example.org).
BUT, i sent one successful email to email@example.com
I dont know how and i dont know why.
