    Dear All,

    I have CENTOS 6.5 x86_64 - WHM 11.42.0 (build 21) - Exim, Dovecot

    When send email get timeout like this:
    ---
    Connecting to gmail-smtp-in.l.google.com [74.125.196.26]:25 ... failed: Connection timed out (timeout=5m)
    LOG: MAIN
    gmail-smtp-in.l.google.com [74.125.196.26] Connection timed out
    Connecting to alt2.gmail-smtp-in.l.google.com [173.194.66.27]:25 ... failed: Connection timed out (timeout=5m)
    LOG: MAIN
    alt2.gmail-smtp-in.l.google.com [173.194.66.27] Connection timed out
    Connecting to alt3.gmail-smtp-in.l.google.com [173.194.65.27]:25 ... failed: Connection timed out (timeout=5m)
    ...



    Telnet command result:
    ---
    srv1 [~]# telnet gmail-smtp-in.l.google.com 25
    Trying 74.125.196.26...
    telnet: connect to address 74.125.196.26: Connection timed out
    Trying 2607:f8b0:4002:c07::1b...
    telnet: connect to address 2607:f8b0:4002:c07::1b: Network is unreachable

    When stop iptables the and make telnet give the same results

    I can receive email without any problem.

    Hot to fix this issue ?
    Thanks for your help.

    Hello,

    Please try a traceroute to those servers google servers/ips from the server. Are you able to reach them successfully ? "Network is unreachable" seems to be an issue here.

    Hello :)

    Is this only happening when attempting to send out email to Google? If so, it means Google has blocked connections from your server's IP address. If it's happening for other servers then you should contact your data center to see if they have blocked outgoing connections over port 25.

    Thank you.
