I'd like to know how to configure my DNS to be able to use a wildcard for my domain and an MX record together. Here is what I've done:
@ IN SOA dns98.ovh.net. tech.ovh.net. (2012052100 86400 3600 3600000 300) IN NS ns98.ovh.net. IN NS dns98.ovh.net. IN MX 1 mail.gestixi.com. IN A 188.8.131.52 * IN CNAME mydomain.com. www IN CNAME mydomain.com.
The problem is that when I check my DNS, I get this error:
MX records shall not point to an alias defined by a CNAME
Because of this error, it look like I can't send mails from some internet providers.
