Blacklists Question

[mohammedking]

Hi guys,

We are running Zimbra with multiple domains on the same host with a single IP. Since we can't really configure Zimbra/Postfix to send from a specific IP and domain, what can we do to protect our IP from blacklists in the event one of ours users is a spammer.

Thought about doing some outgoing filtering but not sure if this is the best approach. Any ideas will be helpful.

Thank you!

Hmmm interesting question ... Filtering is the only real way ... the other alternative would be to limit how many emails a user can send out so that they don't abuse your service and bandwidth.
