Hello
When I check mxtools for my email routing domain i have this warning:
Status Warning dns mydomain SOA Serial Number Format is Invalid
Status Warning dns maydomain SOA Expire Value out of recommended range
Status Warning smtp / isaac mx Cloudflare net Reverse DNS Resolution - No PTR Record found
Status Warning smtp / isaac mx Cloudflare net May be an open relay.
Status Warning smtp / amir mx Cloudflare net Reverse DNS Resolution - No PTR Record found

Is it possible to correct all this warning ?
