    Hello,

    I am wondering if anyone can shed some light on this for me.

    I have a constant steam of emails appearing in my whm mail queue mananger from one domain on the server.

    They appear to be bounce back emails, and they are 'frozen' in the mail queue

    The domain has the following A records:

    (CLIENT DOMAIN). MX 10 remote.(CLIENT DOMAIN).
    (CLIENT DOMAIN). MX 15 (CLIENT DOMAIN).
    remote. A (IP ADDRESS)

    I am at a loss how to stop them.

    Would anyone know how these are happening, or how to prevent?

    I have copied and pasted a typical email below (I have put in (SERVER DOMAIN) and (CLIENT DOMAIN) to hide their identities)

    They all have:

    "A message that you sent could not be delivered to one or more of its
    recipients. This is a permanent error. The following address(es) failed:

    npeter@(CLIENT DOMAIN)"

    with the above ( npeter@(CLIENT DOMAIN) ) not being a valid email address.

    Is anyone have an idea what is happening here?

    Thanks for any help.

    Kind regards,
    Anthony



    The message header and email always appears to be:

    Hello :)

    Is this domain name stored in the /etc/localdomains file or the /etc/remotedomains file? Are you pointing it's email to a remote mail server?

    Thank you.

    Hi guys,

    Thank you for the replies - much appreciated.

    I have answered them below:

    1. why do you have both remote and local MX records?

    --> I don't know why that is the case - it has always been like that (and I actually took the account over from a previous owner, so I haven't changed any of their settings).

    It was previously like:

    (CLIENT DOMAIN). MX 15 remote.(CLIENT DOMAIN).
    (CLIENT DOMAIN). MX 10 (CLIENT DOMAIN).

    however I recently switched the order around to see if that helped:

    (CLIENT DOMAIN). MX 10 remote.(CLIENT DOMAIN).
    (CLIENT DOMAIN). MX 15 (CLIENT DOMAIN).

    2. Is this domain name stored in the /etc/localdomains file

    --> No, it doesn't appear there.

    3. or the /etc/remotedomains file?

    --> Yes, it is there.

    3. Are you pointing it's email to a remote mail server?

    The mail record is a CNAME to (CLIENT DOMAIN).

    The remote A record is pointing to a external IP address - I am assuming this is a remote mail server


    I hope this helps guys - thanks for any insights you can provide.

    Kind regards,
    Anthony

    You may want to try configuring the MX records to use either the local mail server, or the remote mail server. The error message you provided indicates the email account does not exist. This likely occurred because the mail was routed to the wrong mail server.

    Thank you.
