In response to changes in the CA/B Forum's 'Baseline Requirements' and Mozilla policy, Comodo has implemented revised Domain Control Verification methods and policies. Starting at 19th July Comodo activated new rules for HTTP/DNS validation.
Email based DCV will remain the same process. DCV emails will however 'time out' after 30 days.
HTTP(S) based validation will change the location of where the text file must be placed, and some of the content of the file.
DNS based validation will change the format of the CNAME record and where the record points to.
