3 options, in order from least to most verbose:

host -t mx mydomain.com
nslookup -q=mx mydomain.com
dig -t mx mydomain.com

The difference is largely a matter of personal preference; I tend to use host, but if you want full details about exactly what you're getting back from the server, dig is the way to go.

The question explicitly asks about command line. The online service opened in a text terminal in browser like links is not very well arranged. –  pabouk Nov 5 '13 at 12:16
