I was actually looking at the comodo website to figure out if I can submit revokation on my own (we've got the key after all...). Gave up after looking at 20+ pages. Apart from a login site for email cert revocation, I can't find any reasonable contact.
Comodo website is not that good apparently.
Edit: in the document posted by brohee: (about authentication for certs revocation) "OR the Subscriber
must be able to send an S/MIME email signed with the private key associated with the Certificate". That's doable :)
4.9.2 Who can Request Revocation
A Subscriber or another appropriately authorized party
can request revocation of a Certificate. An authorized party includes an RA, regardless of whether on behalf of the
Subscriber may request revocation through their account.
Other parties may report suspected Private Key
Compromise, Certificate misuse, or other types of fraud, compromise, misuse, inappropriate conduct, or any other matter related to Certificates, in the first instance, by email to sslabuse@comodo.com.
