    Please help.
    I just moved to a new server.
    I've done the configuration of rDNS
    with 210.16.xxx.xx -> server.example.web.id

    I've test sending email from my domain (someusr@example.web.id) to my Yahoo and Gmail, but the email never received.

    I've check the Mail Delivery Reports and the result was "Connection timed out"

    But receiving email from Yahoo, Gmail or other just fine.
    Please help what should i do..
    I have very little knowledge

    Hello,

    Please do verify the rDNS is properly set or not. You have to check at mxtoolbox.com/ReverseLookup.aspx

    Also, you have to check MX record is correct for you domain name at intodns.com

    Your rDNS wouldn't have anything to do with a connection timeout.

    Please go into SSH and run:

    Code:
    tail -f /var/log/exim_mainlog
    then go into WHM > Mail Queue Manager

    click one of the emails in queue and click "Deliver Message Now".

    Watch SSH and paste the full output once it times out.

    Actually... what happens if you simply run:

    Code:
    telnet smtp.gmail.com 587
    and paste the output, you may have to wait a bit for it to timeout.

    If you get:

    Code:
    -bash: telnet: command not found
    first run:

    Code:
    yum -y install telnet

    Hello,

    Are you able to send out email to remote mail servers that are not Yahoo or Gmail? You can test this with a command such as:

    Code:
    telnet remote-mail-server.tld 25
    Replace "remote-mail-server.tld" with the hostname or IP address of a specific mail server you are attempting to send email to.

    It's possible your hosting provider has blocked outgoing traffic over port 25, in which case you'd need to contact them to request they lift that restriction.

    Thank you.
