    I have a problem with DNS records (MX and CNAME), when I create a MX record with the value mxa.mailgun.org BIND adds .example.com at the end.
    I describe my problem:
    I create a new MX record with the value:
    mxa.mailgun.org
    And a CNAME record with the values:
    email mailgun.org

    However, when I do a MX Lookup in MXToolbox, the saved value is
    mxa.mailgun.org.example.com

    So I checked the file /etc/bind/pri.example.com
    The Cname and MX records look like this:
    Code:
    email 3600      CNAME        mailgun.org
    @ 3600      MX    10   mxb.mailgun.org
    @ 3600      MX    10   mxa.mailgun.org
    Nonetheless the values in /etc/bind/pri.example.com.signed have the domain name at the end, wich are the records showed by MXToolbox.
    Code:
    3600    MX      10 mxa.mailgun.org.example.com.
    3600    MX      10 mxb.mailgun.org.example.com.
    3600    RRSIG   MX 7 3 3600 (

    (Records censored) lol
    I´ve tried to edit that file, but I think it´s pointless. I think it´s because of DNSSEC, when I edit the record manually the values don’t coincide with the RRSIG signature, so the changes are ignored.

    What can I do?
    Thanks in advance!

    use mxa.mailgun.org. instead of mxa.mailgun.org (note the dot)
