The skadnsmx program

skadnsmx reads a domain name on its command line and performs an MX request on it.

Its interface and behaviour are exactly the same as dnsmx's. Actually, this command was written to test skadnsd.

What is interesting in skadnsmx is its source code: it shows a simple example of using the skadns library.
