Why does it matter if there's a naming collision between DNS domain names and file names?

Discussion of config files for SpamAssassin and Postfix has
intermittently been matched by URI DNSBLs. Some years ago I discovered
just how widespread dumb bounce models were when I talked about the
master config file for Postfix on the Postfix Users list, the same
week that someone was spamvertising URLs under master (dot) cf.

so ns.cf blocks my named now, i cant resolve any cf domains with it

time to change imho

I recommend chasing who is treating those as URLs.

That would be SpamAssassin itself. The policy of treating anything matching '[-a-zA-Z0-9_]+\.<known TLD>' as an URI in all contexts dates back to v3.3.1 at least. See https://bz.apache.org/SpamAssassin/show_bug.cgi?id=6716 and note this scan of a recent message:
