Hi,
Some networks are known to be more accommodating spam here.
I wouldn't actually call these "ISPs"
These are usually one-man-show hosting companies with either no care or
knowledge.
I don't think it would hurt anyone if you are to block their complete IP ranges.
But going back my logs by a month, it seems I got some too.
They don't send to generic mail addresses and they seem to be using legit user
mails. I presume they operate on a mail list.
And they seem to use lots of useless TLDs with different domain names in their
spams and as they seem to hit
UriRBLs (centuryfear.guru:SURBL,SURBL,URIBL,SPAMHAUSDBL)
or
PreRBLs (TRUNCATEGBUDB,BLOCKLISTDE)
they get denied instantly
Did you try contacting via abuse?
