Hi I recently ran my domain through a few sites to check the configuration was done and was surprised by some of the warnings that were reported.
From intodns.com I noticed one warning and one error being reported and wasnt sure if this was something I could solve my self of an improvement needed to mailinabox.
The MX records that do not seem valid hostname:
This can cause problems
Your SOA RETRY value is: 86400 . That is NOT OK
I also ran it through hardenize.com which reported the following warning:

There are issues with this site’s SMTP configuration.
