Question
Poor Mail Reputation at http://www.senderbase.org
Hi,
We recently changed our mail server from one ISP to another. Now I am getting some outbound mail rejected. On one email from Dell it stated that our mail server's IP has a poor reputation and it gave me a link to www.senderbase.org. When I checked our new mail server IP on that site it stated that we have a poor reputation. My ISP offered to change the IP and it also made me aware of the fact that the IP we currently use is not black listed, anywhere. Could it be something to do with my SPF record? Please help! BTW the ISP we use is a very reputable company in the USA. Any help would be greatly appreciated.

Why is the reputation Poor?
These are the most common reasons:
* Your email server or a computer in your network may be infected with malware and may be used to send spam.
* You may have an insecure network which is allowing other parties to use your network to send spam.
* Your email server may be misconfigured and might relay spam.
* You may be utilizing a dynamic IP that is not allowed to relay email directly to the Internet.

Sounds like the problem is not inherited then.
If you are not on blacklists, then you are presumably not sending spam, so what are Senderbase upset with?
Please have a read of their about page: http://www.senderbase.org/
Then run through my FAQ posted in my initial link to see if you are setup properly.

I have an FAQ regarding problems sending mail to specific domains so you can check your domain is setup in the best possible way to make sure your mail gets to it's destination with as few being rejected as possible:
http://www.it-eye
The problem with having a poor reputation is exactly that. If the IP Address you have has a bad reputation, it is only time that can heal this.
Sure - you are not blacklisted, but you seem to have inherited a suspect IP address and changing this may only provide you with another suspect IP Address, but on the other hand, it could help.
Not everyone checks against senderbase reputation scoring, but obviously Dell do.
