    Exim failed by itself

    I have a busy cpanel mail server

    Very often now and then, i have 2 issue coming up:

    1. Unroutable E-mail bounce back message
    The message looks like this:
    [email protected]
    unrouteable mail domain "gmail.com"

    I have already set "unlimited" mail per hour on cpanel itself and it should not be giving me this message but it does again.

    2. Exim failed by itself (SMTP Error while sending out e-mail)
    I am using Outlook Express & Thunderbird, sometimes while sending out the e-mail, it gives SMTP error popup message.The e-mail was never sent out. I can only solve this problem by restarting exim manually.

    What are the permenant solution for both of this issue?

    Check your /etc/resolv.conf and make sure it is setup correctly.

    Also, login to WHM and remove this:

    Server Configuration >> Tweak Settings >> Track the origin of messages sent though the mail server by adding the X-Source headers (exim 4.34+ required)

    Inside /etc/resolv.conf are my server IP (xx.xx.xx.xx)

    nameserver xx.xx.xx.xx
    nameserver xx.xx.xx.xx

    x'ing out does not help us. Have you checked to make sure the nameservers are accepting connections, and querying remote hosts?

    check your /var/log/exim_paniclog to make sure the domain isn't running into one of those hourly limit errors. Run this, and send back output

    tail -n 20 /var/log/exim_paniclog

    Nothing inside panic log. Plus i have set email to unlimited per hours as mentioned earlier. How do I check if the name server are accepting connections?

    I actually just rebooted the server and it works fine again..

    for each nameserver, run this:

    dig gmail.com @123.123.123.123

    Replacing 123.123.123.123 with the server ip.
