    I found it is not possible to use underscore in CNAME record even it is allowed in RFC:
    How is it possible to permanently add underscore to cname record like this:
    k1._domainkey 3600      CNAME        dkim.mcsv.net.
    I edited zone file directly but it will be removed with next DNS change in ISPConfig.
    Thank you.

    Hi Till,
    thank you. Is it way to add CNAME record with underscore manually and avoid deleting by ISPConfig?

    change the validator in interface/web/dns/form/dns_cname.tform.php from
    'regex' => '/^[a-zA-Z0-9\.\-\*]{0,255}$/',
    'regex' => '/^[a-zA-Z0-9\.\-\*\_]{0,255}$/',
    @till: you can mark this task as solved.
