Getting a list of .bid IP's
Is there any way to get a list of all the .bid IP addresses so they can be used by pfBlockerNG?
Getting hammered by spam and 98% of it is coming from the .bid network. I keep adding the IP's manually as they spam me but each time from a different IP but all belonging to the bid domain.

I don't use pfB but could't you just add *.bid to the DNS blackhole or something?
No because they are not asking my DNS for an IP so it can't reject it. It would need to do a reverse lookup on the IP and get the name and then block on that and I don't think pfBlocker does than. That is why I need the IP range or addresses to enter in which does work.

.bid is just a TLD and any associated IP addresses would be totally random. There is no natural association between domains and ip addresses.
Are you certain the servers are actually in
.bidand not just using that as an e-mail address? If it is the latter, your mail server can likely be configured to reject any mail from
No not the email address. Have been tracking the header data backwards. Yes some of them may be spoofed but certainly not all. The email addresses have all sorts of stuff in them so not reliable to exclude by that either. I did try and it was more work than simply hitting delete. Even tried filtering on subject lines.
Was getting heaps of those "I put a virus on your computer and watched you do naughty things. Pay me in bitcoin" that seem to be doing the rounds at present. Got 20 of them in three days at one point. Filter put a stop to most of those.
You do understand the IPs that are are registered to domains that are in the TLD .bid would be changing second by second across the planet right..
IP has zero to do with DNS - zero... I can register ANY IP to a FQDN I have..
So host.domain.com can point to 22.214.171.124, or otherhost..someotherdomain.bid could also point to 126.96.36.199
For a PTR record who owns the IP block, and controls this space with their registrar can point the netblock to a NS for resolving the reverse... So it might resolve, it might not resolve that owner can have 188.8.131.52 PTR resolve to anything they want, etc..
How about you post up some headers of this spam, so we can see some IPs your wanting to block..
Okay here is one that just came in. I have remove the machine names

In pfBlockerNG-devel is a new Feeds tab. You can try to add the "Mail" specific IP blocklists...
That 185 range is full of crap.... Alienvault feed would have blocked that event from getting thru. But jimps advice was good... You can do a good chunk of this with the mail server.
Recommend to add some RBLs and RHSBLs atleast from Spamhaus ....
Thanks. Will try that. I tried to add them to exchange but Microsoft killed that and now you need an Edge Server to do the IP block lists from Spamhaus and I can't afford the extra license for the Edge Server.
Will check out the feeds tab.
Tried to add the Zen Spamhaus list and got what I originally got when I tried it.
Says it cannot resolve zen.spamhaus.org and I can't resolve it with ping or any other tool.
why not just block all of Turkey ;)
What comes out of their other than crap? ;) Just use pfblocker so some of those spam countries can not even talk to your mail server..
Do you do business with anyone in Turkey?
That IP is on a billion freaking blacklists
If your mail server can not talk to black lists maybe you should be fixing that...
Along with what johnpoz is saying, I would never run a mail server without zen.spamhaus :) Plus there are a few others that will really help in limiting spam.... I would also move away from Exchange into something postfix based like Zimbra.
Zen does not appear to be active. Tried looking it up on the DNS and says it is down.
Moving away from Exchange is not an option as there too much money spent on it to simply ditch it. Others have help pay for this as well. As I said with the Edge Server IP block lists can be used but again it cost more license fees for what is basically a relay just to filter spam. If I can filter most of the spam then I am happy.
Zen does not appear to be active.
Zen is not down, you query it with a reverse ptr like so:
Then the response tells the mail server if its listed in the zen database based on the IP in the answer (ie: 127.0.0.11)

Yup there is your IP you posted which .3 mean
"Direct snowshoe spam sources detected via automation"
What does your exchange box use for dns? You can not be using say google or something - they not going to allow that to work..
Ah thanks for explaining how the spamhaus works. No my exchange server uses the local DNS on my domain controller. When it can't find an answer it will forward which now goes to pfSense and out from there.
now goes to pfSense and out from there.
And pfsense is resolving - or is pfsense set to forward?
Do a simple dig or nslookup - do you get an answer from zen.spamhaus.org? if not you need to figure out where the dns is breaking down..
But for example if I ask google the same question I get back

Because they do not allow it to work that way.. You need to be asking them directly, if you need to forward vs resolving your stuff - then you could setup a conditional forwarder for spamhaus so that you ask their ns directly.
pfSense is doing the resolving. I was querying spamhaus wrong so my bad there.
However I have added Alienvault to my IP block list and have not had any spam for the last two days. Still getting stuff from my webserver provider from the control panel but working on that now.
and have not had any spam for the last two days.
Music to my ears :)
