How to find where email server has been blacklisted
Hello
I'm trying to figure out why some emails get lost, which most likely is due
to emails killed by ISP spam filter due to high spam score these lost email
have.
How to find out if some mail server is blacklisted and where?
Is there any central database for queries from all different blacklists?
Also IP based search is required and data when and why.
IP based search may be needed, as server under question has it's mailbox
hosted with ISP, but I believe that still the virtual server can be
blacklisted separately based on it's static IP and not the whole ISP mail
server.
Additional side effect is that emails sent inside company get lost more
often - I believe because they virtual server is blacklisted somewhere and
therefore emails sent always gather higher spam score.
So the question is to find out where it's blacklisted?
Thanks for any help and guidelines how and where to continue!

I've been using this one:

I'm not sure what information you can get if you are listed. I have not
had that problem so far.

Hi,
Then something is broken at your end ...
I see 4 icons ... timeout, listed, non-listed and offline.
Or am I missing your point here ?

That would be a very useful site, except that it shows the results as colour-coded icons, and I see the listed and not-listed icons as identical.

I wrote a Perl app a while ago to do lots of DNSBL lookups -

If I look up 127.0.0.2 it should be listed by most DNSBLs as it's a test IP:
