    On my linux server, I can't send email only to gmail/google apps users. All emails sent from this server is bouncing back with an error:

    For gmail.com users, getting below error:

    Code:
    my-gmail-account@gmail.com
    retry time not reached for any host after a long failure period
    Google apps users, getting bounce back email with below error message:

    Code:
    my-google-apps-email-account@gmail.com
        SMTP error from remote mail server after RCPT TO:<my-google-apps-email-account@gmail.com>:
        host us2.mx3.mailhostbox.com [208.91.199.226]:

        550 5.1.1 Please see
    http://support.mailhostbox.com/email-administrators-guide/error-codes for
    explanation of the problem.
    Got below error from error log on the server:

    Code:

    Also when we stop firewall on the server, it successfully delivers email to gmail and google apps.

    Can somebody help me to find exact reason behind this issue ?

    Thanks,

    Please ensure that your firewall allows connections to ports 25, 465

    TCP_IN port 25 and 465 are already enabled.

    Also when we stop firewall on the server, it successfully delivers email to google apps user account, but not to gmail user accounts.
