UCEPROTECT is a widely known fraudulent RBL, and as such, no legitimate
service provider should be using them.

Hello all,
I have noticed that every time, without fail, that I post anything to
this list, I get added to the following blacklists:
UCEPROTECTL2
UCEPROTECTL3
I have communicated with my web host, who says that the problem lies
with IP address: 51.161.115.83
Is this your IP address? Please check!
My understanding is that one rotten apple spoils the barrel, in the
sense that if this IP address is spamming, all of the web host's IP
addresses will be blacklisted. They do not seem thrilled that this is
happening on a regular basis.
Is this happening to anyone else?
Thank you,
Katie
