The available Mandrill features are completely optional.
If your application does not need to programmatically process incoming mail (for example, via email for the blogging platform), and you cannot easily do this without using Mandrill, you can pretend that the incoming Mandrill functions do not even exist.
If you need simple old inbox, just set up your MX record as usual.
Even if you need to use Mandrill's inbound features, this is best done on a subdomain. To cite documents :
All emails sent to this domain will be sent to Mandrill instead of traditional email mailboxes, so it is recommended that you use a subdomain, such as "inbound.yourdomain.com", which does not yet exist.
