Problemas con POSTFIX

[elielbeck]

Hola
De instalado una copia limpia de POSTFIX y se ha configurado automáticamente porque lo he instalado con YUM INSTALL.

Pero el problema es que el servidor en si (SMTP y POP3) aparece que esta ON y que funciona perfectamente pero no puedo enviar ni recibir emails.

He enviado un email de prueba a un gmail y me ha devuelto esto:

Código:

Esto es: google (gmail) te ha rechazado el correo porque "nuestro sistema ha detectado un ratio inusual de correo no solicitado procedente de su dirección IP. Para protecier a nustros usuarios de SPAM hemos bloqueado el correo enviado desde su dirección IP..... por favor visite http://www.google.com/mail/help/bulk_mail.html ...."

Al parecer desde tu servidor (82.165.27.80) se han estado enviando correos SPAM a direcciones de gmail.
