Can I Use whmcs to offer email hosting?

Hi,

I'm looking into offering email account hosting to my customers I was wondering if this service can be handled by whmcs.

I would like customers to be able to register a domain, once register they would then have the option to purchase various email account packages.

The process of connecting the domain to the email (also creating) accounts should also be automated.

Anyone know if this can be done with whmcs?
