Your host will not see any of the traffic going to your donated MX.
When you donate a MX record the DNS files are updated to translate your mail domain name to the IP address where "your" mail server is located. In this case "your" mail server is controlled/hosted by Project Honey Pot NOT your host where your website is located.
A longer answer involves how the internet uses DNS servers to find things on the internet.
The internet uses IP addresses (i.e. 213.123.456.101) to locate things. No one wants to remember something like that for your_domain_name. The DNS is a big lookup table that translates your_domain_name to an IP address (a.b.c.d) when someone needs to know where your website is so they can see what you have to say. The same thing happens when someone wants to send an email, except the MX record is used to find where your_domain_name mail server is located (IP address w.x.y.z).
The DNS service is a distributed service not connected to the bandwidth you are paying for with your host.
Thanks for your donation and welcome to the fight!
