Choose a name in a domain that you control, in the form of 'hostname.domain.tld'. Use this as the hostname, mailname, in your MX records, and so on. The reason for this is that records that contain the IP address may get you filtered. If you do not have a domain you control, register one. Avoid .info, .pw as top-level domains for this. Make sure you create the A record for '46.21.105.38' first. Many automated PTR control panel tools will check whether it exists.
