E-mail is very important asset. It is used everywhere, from social networking to bank account. In most cases people have one e-mail address which is shared with all services they use. It may have bad consequences...
First: in event of data leak/security breach criminals can easily locate all your accounts and use this information in malicious way. Second: e-mail is used to track your activity and also to profile you. By using random aliases trackers are unable to perform their job efficently. Third: random aliases prevent phishing attacks. When you generate an unique alias which is used by you at only one service - you can be sure that no one else can send legitimate e-mail to the alias.
Alias is an e-mail address that is attached to your primary e-mail address (real one). Usually aliases are used to identify incomming mail, for example: john.snow@north.com can use this primary address for friends, but for ones who know his secret he can use alias aegon.targaryen@north.com. Now he is aware that mail sent to this alias comes from one who knows the truth.
c0x0.com uses same principle to hide your real e-mail address. Usually c0x0.com aliases looks like this: f1de1c49df@c0x0.com
No. Disposable addresses are short-living and designed to be used once and then thrown away.
We designed c0x0.com aliases to be permament, "normal-living" e-mails connected to your real address. Of course you can delete them at any time and regenerate new ones (limits apply) but that is not primary purpose. If you are looking just for disposable e-mails probably there are other services that you will be happy with.
Not at this time. c0x0.com is forwarder only, we do not keep, process, store any e-mails at our servers. E-mail is delivered only to verified endpoints(e-mail addresses)
In the feature we might allow sending mails using our domain.
