How to determine if my mail server is configured correctly?

Question

Does anyone know of an online service (similar to the ones that tell you if a site is up or down) that can connect to a specified mail server and perform checks to see if it is configured correctly?

If not, does anyone know exactly what these checks should be? (https://www.nearlyfreespeech.net/about/email gives an interesting stance, but looks to be not very specific)

The specific mail server I'm trying to see if it is configured properly is mx.adammw111.co.cc , but I'd rather find a automatic checker outside my own network than do many manual checks.

Thanks,

Solution

Have you tried http://mxtoolbox.com it can check to see if you are blacklisted and you DNS records are correct, but doesn't really tell you if your configuration is correct.

These are strictly DNS tests.
