MAPS Problem

[Effektor]

After enabling MAPS in the Plesk interface the clients get receive a Outlook failure.

The Message says their IP is listed at spamhause.

If I check any IP of our Server at spamhause I do not find any failures.

So how does MAPS work and why do they receive this failure?

Need Help....

They are receiving this error because the ip address they are sending the email from ( thier local ISP ip address ) is listed at Spamhaus.

It is not your server ip address that is listed. MAPS checks with spamhaus for ALL emails even if smtp authentication is required by your server.

So what should be the next step for me to do?

Enabling MAPS will block our Clients from sending mails.
If I do not enable MAPS our Clients receive tons of spam.

How do I decrease the amount of spam on our Server without blocking our clients?

Ideally, have the ISP's stop the spammers and ask Spamhaus to remove the ip addresses from their list,

Realistically, you can ask MAPS to exclude checking certain ip addresses by adding them manually to the smtp_psa file like this:

server_args = -Rt0 /usr/sbin/rblsmtpd -a xx.xx.xx.xx -r relays.ordb.org..........

This will exclude this ip address from being checked by MAPS
