Hi Michael, thank you for your answer.
Sure, the first pool we are warming up is the range from 212.115.96.5
to 212.115.96.36.
In this range the only IP with a correct reputation is 212.115.96.31,
you can just compare the result of 212.115.96.30 and 212.115.96.31 to
see the differences.
They are on the same pool so they has the same history of sent e-mail.
Other ranges was having a similar behaviour but we stopped them so they
actually loose the reputation.
Any help is appreciated.
Stefano

Can you share the IP (range) so we can maybe give some opinions on
what the issue might be?
Aloha,
Michael.

*Subject:* [mailop] Crazy Sender-score value of 0 instead of 96-98
Hi,
I installed a new instance of my e-mail platform for a customer of my
company but a very strange things happens during the warm up of the
new sending IPs.
Quite all the IPs (Assigned us directly from the RIPE) got a sender
score of 0 instead of the usual 96 -> 98 range.
Fortunately, few of them are on 97 as expected.
No blacklist have been achieved and no bad indicators are present
after a couple of months of consistent sending.
We are correctly deactivating permanent bounce and feedback loops as well.
The 97 score IPs has the real sender domain linked to the IPs on
senderscore (as it happens usually).
The 0 score IPs hasn't any sender domain linked, in some cases they
have the platform domain as unique sender linked (that is not a sender
in any way and is not used as any sender in the e-mail sent, nor in
return-path).
Every sending host/IP is sending mail from 5 well known sender in a
round robin schedule (so they should achieve quite all the same
reputation but it doesn't happens) actually the rate is the same and
it's quite low (7,5k/IP/day).
Every IP/host is a clone VM so thgey are exactly the same except for
IP and host name; every host has the same DNS/PTR/SPF/MX configuration.
Every sender sign the e-mail with his DKIM and has the Sender-ID (SPF)
record over the sender domain.
The deliverability cut off is from 90% of the 98score to the 30% of
the 0 score and they are sending exactly the same things/amount/databases.
Anyone experienced this kind of issue?
Can someone share any sender-score contact on order to verify this
issue with them?
Thank you guys!
Stefano
