    Hy guys.

    First of all, I'm totaly new in lynux.

    I get a debian mail server installed and configured step by step like on the site.

    When i try to send a mail i get the following error:

    An unknown error has occurred. Account: '', Server: '', Protocol: SMTP, Server Response: '421 Cannot connect to SMTP server (, connect error 10060', Port: 25, Secure(SSL): No, Server Error: 421, Error Number: 0x800CCC67

    Anybody can help me?

    Thanks a lot

    Your ISP is blocking ports(access) to your SMTP server. (I think that you are on RDS - ro user myself)
