How to setup an incoming spam-filter


How to order and configuration an incoming spam-filter?


In order to setup an incoming filter on domains, first one need to have a domain.

It does not matter if the domain is with Openprovider or with an other registrar.


Step-by-step guide:,

1) Log into Openprovider control panel and navigate to SpamExperts>Add new filter.

2) On the next screen:

- enter the domain name

- select the desired filter (incoming filter / Outgoing filter / E-mail archiving)

- enter mail-server host address




3) Click Save

Now the incoming filter for the domain has been created but, not yet configured.

4) Add MX records to the DNS zone of the domain.

If the domain is with Openprovider and is also using Openprovider's NS, the following MX records will be automatically added by our system to the DNS zone.

Otherwise, you will have to add them manually.

  • (with priority 100)
  • (with priority 200)
  • (with priority 300)

Be sure to never add other MX record(s) together with the Spamexperts records: this will result in only partial filtering of the e-mail, and not remove spam completely!

In case the DNS zone isn't created yet - navigate to DNS management>New DNS zone and create new Master DNS zone. 

In case the DNS zone is with Openprovider, navigate to DNS management>DNS zones overview and click on the domain in the list.

Once DNS zone details page is opened - click on Enable checkbox. Once page is refreshed the MX records will appear automatically added in to the zone.



5) To configure the mail server to accept the spam-filter connections and treat them as 'trusted'.

This can be done by whitelisting the domain-name in the mail-server.

6) In some cases SpamExperts server also needs to be added to the SPF record of the domain DNS zone.

In order to do this, please add the follow SPF record with the content below:

"v=spf1 -all"

Or add -all to the existing SPF record.


For more information about the incoming spam-filter can be found in the knowledge base of SpamExperts.
