Issue E-mail - User IP being verified in RBL

[ViaHosting]

The IP used in my house is in a RBL.

All the messages I send, are being classified as "SPAM" or are being refused.

Even if I use a webmail to send a message to myself .

The server is verifiyng the client IP, not only the server responsable by the relay.

Before doing anything else, you need to check to make sure non of the e-mail accounts on your server have been compromised and are sending spam.

If they are, deal with them first, as if you try to remove your IP from the Spam List, you'll just get re-added to it.

Once you're 100% confident you've dealt with any and all accounts.see here to request your IP be removed from spam list: Blocklist Removal Center - The Spamhaus Project

But the problem is not in MTA.

Let me give an example:

If I connect to the webmail, from my house with IP (x.x.x.x), to send a message to my wife, in the same domain.
The message is refused because my house IP is in a RBL.

This also happens if I use Outlook, with an authenticated connecction.

Prior, the client (user) IP was not verified in RBL.

In my understand, the RBL check is for the relay between servers, not between client and server. Once the client has alredy being authenticated.
