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,

If you mean that you want to check for whether your mail server will act as a open relay (a bad thing) then you can use the online checker located here http://www.abuse.net/relay.html. Just put in your mail server IP address and leave the other options blank.

You can also try http://www.mxtoolbox.com/ to provide the extra header checks and SPF records.
