Senderbase
Jul 7, 2009
Let me start this thread off by saying I can not stand spam. Any reports that I get, I address immediately (within 24h), providing that they're given to me by the provider to fix!
That said, I just got nullrouted, not once, but twice by Hivelocity, due to a rather bogus senderbase report. I'm not going to discuss the nullrouting right now, but the actual fact that this ip address is IN senderbase with a poor reputation (WTF).
Looking through the links there (google abuse, RBLs, etc), nothing is off, the ip address is NOT listed anywhere, there has been absolutely NO spam from the server itself (I checked logs twice), yet NOTHING unusual came up.
Proof? I've yet to receive any, or any explanation as to WHY this is listed (I know, Hivelocity can't prove it, and that's fine, they're only doing their jobs), but this is just nothing more than an annoyance.

Twice in two years now, as a very responsible host with ZERO tolerance to spam (incoming or outgoing!), I have been hampered by the efforts of the anti-spam "reputation service" offered by [url]
We host something like 2000 websites across a cluster of servers, and while we do everything possible to prevent spam, it's inevitable there will be the occasional outbreak.
A couple of days back, sure enough, one of our hosted sites was compromised. As far as I could tell, the culprit was too simple a password. There were no signs of compromised scripts, permissions, anything. Just a spam script uploaded via FTP from a foreign IP address. We do have limits on password strength now, but may not have when this account was set up.
Anyhow, within 120 minutes or so, we had removed the spam script, blocked the offending IP, secured the site and delisted our IP from the ONE RBL it appeared on - Spamcop.
You would think that would be the end of the story, right? Wrong.
Here we are, over two days later, NO listings on any RBLs, NO further spam from ANY of our servers. What Senderbase reputation do you think that server has? Poor.
This is an IP that as far as I know has NEVER had a spam issue, other than the single outbreak two days ago.
The net result of this "Poor" listing is that we have now had outgoing email sitting in our mail queue for 50+ hours because the recipient mail systems are STILL blocking us based on our "Poor" reputation.
Furthermore, I quote directly from the Senderbase site: "Why is the reputation Poor? This host is sending spam!". That one really tipped me over the edge.
As I say, this is at least the second time two years running that this has happened to us. Single spam problem; Cleaned up quickly and efficiently; Wait on Senderbase for days.
It is hard enough dealing with spammers and problems like this, without having to fight the "good guys" too. All I can say is that I will personally NEVER use, nor recommend, the services of Senderbase or Ironport.

I have an email server one account of which is compromise and resulted in my senderbase score as poor. How long will it be reverted back to normal or neutral? Anyway I can hasten the speed?

I would be interested in knowing if anyone has used the data returned from Senderbase.org as part of their antispam evaluation. And if yes, have you found this to be effective compared to traditional IP blacklists like SpamHaus ?
