1. Configuring MX Records
To use Incoming Filtering, you need to point the MX Records for the domain to the SpamExperts Hosted Cloud routes.
First remove any existing MX records from the DNS of your server.
Then set the MX records with the following priorities as SpamExperts describe:
- mx.spamexperts.com (Priority 10)
- fallbackmx.spamexperts.eu (Priority 20)
- lastmx.spamexperts.net (Priority 30)
Now you will need to allow DNS to propagate for SpamExperts to recognise the MX records have changed and to filter the emails.
No further configuration is necessary. An email will be routed through the SpamExperts Cloud System initially, Spam filtered out, and the resulting clean emails forwarded on to your local mail server.
2. Setting up DKIM
If your sending domains already sign with DKIM, then this should not be changed.
SpamExperts will simply forward the DKIM signed messages along to the recipient.
If there is no DKIM signing, you can decide to either sign this on your sending MTA, or sign with SpamExperts.
It's not obliged to sign with DKIM, however it often helps to "authenticate" as much as possible your senders.
3. SPF Record Configuration
Create a TXT record for the outgoing sending domain with the following details:
"v=spf1 include:spf.antispamcloud.com -all"
If you already have an existing SPF, simply add
- a:6205.submission.antispamcloud.com
- a:release.antispamcloud.comto your existing record.
