So it seems to me that your mail provider is passing the buck and saying
"Government censorship!!!" when what actually happened is that they
delegated their spam filtering to some garbage commercial filtering
system such as UCEPROTECT or similar.
But maybe that's just me being cynical.
Nope. You're not being cynical. My clients have this issue with their
clients' mail providers using crap RBL services all the time. ‘Cause, yes,
blocking a whole subset of IPs for ‘bad neighborhood’ makes you a hell of a
lot more money selling "express delisting" to idiots.
