I don't know too much of the specifics but I persume they are sending
from different ports due to the fact they will be sending mailt o many
different customers.

They are actually attempting to deliver your email by SMTP which is part
of the service, it allows email to be "pushed" to your machine so you
don't need to keep checking to see if new email is available, it also
allows you to reject email based on who it is to or from.

It's part of the service, SMTP and static IP are 2 services that Demon
offer that distinguish them from many others.
