I'm having an issue with SenderBase. My IPs are not blocked in any BLs but people who use SenderBase/Ciscos stuff do not get my emails. Is this because my email system is setup poorly?
They list the following:
- 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.
I have just my site running CPanel. As far as I know there is no spam or abuse. What should I check to ensure that the mail systems (Exim) are up to standards? I have the server pretty well configured so I just can't see the system being abused without me knowing it.
What standards should I be ensuring my e-mail server aligns up to?
