    That looks like a .Net Framework error on your server. I'd first run the System File Check and if that didn't help I'd remove, reboot and reinstall .Net 4.

    I think I remember something about SmarterTools saying some network cards caused this or a similar problem. Either way the problem seems to be inside your server. Check the Event logs and see if they give any more info.

    You mail server is not reachable on port 25. It looks like one of several issues:

    1. You have not mapped your port numbers to the IP ADDRESSES and hostnames inside SmarterMail.

    2. Port 25 is closed on your firewall

    3. You do not have the three MX HOSTNAMES setup on the correct IP ADDRESSES in your SmarterMail configuration

    4. You do not have the IP ADDRESSES assigned to each of the three hostnames you are using for MX records assigned to the correct IP addresses

    PM me if you need assistance on this.
