Is it safe to use their email service?

I'm still trying to figure out how this works. I may have sent some
mailing list email to spamcop.net. Instructions on the site tell you not
to do this. Something about adding the mailing list server/host to the
system so it doesn't get blocked.

It's a little confusing.
