Hi we have a strange problem
Our hosted site is on a shared platform with a single IP and our emails are on a hosted platform from another provider.

If the IP of the website ends up on a blacklist our emails are not accepted by some clients due to the blacklist however the messages are sent from another server.

Is there any way to avoid this without getting a separate IP for my site?

Some blacklists  (actually RBL is for Realtime Black List) are based on IP, others are based on domain name. If you're being blocked because of the domain name, you're kinda stuck -- you'll just have to get off the blacklists.

The fact that your web server and email server are on different physical (or virtual) machines doesn't matter much though if they share a PUBLIC IP address (Same provider using NAT perhaps?)

Use the site VALLI.ORG to check both (assuming 2) public IPs and the domain name. You should get a better handle on what's happening after their results show up.

Would it be safe to assume your web server is sending out SPAM (intentionally or not won't matter -- either way you say your webserver is what's being blacklisted)... if this is unintentional, consider disabling outbound mail on your webserver (or send it through a smarthost to filter it).

In any case, SPAM prevention is a kind of WILD WILD WEST out there - lots of people playing Sheriff and enforcing their own "laws" (or interpretations thereof).... no real guiding authority, and most of us Mail Admins are stuck trying to play by everyone's separate rules.

All I can say is: good luck!
