What is the best way to lookup MX records for a domain from the command line?

3 options, in order from least to most verbose:

host -t mx
nslookup -q=mx
dig -t mx

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.

No, the option the LEAST verbose is dig +short MX – bortzmeyer Sep 21 '09 at 7:19

nslookup -q=mx

dig -t mx will work as well.
