How to Set Up SPF for SpamExperts?

SPF records are used to help prevent email spoofing. They help to ensure that only authorized servers can send emails on behalf of your domain. SPF records can help to improve your email deliverability.

How to Configure SPF for SpamExperts

• Sign in to your DNS administration interface.
• Select DNS Template under Tools & Settings
• You must change the DNS TXT record for SPF.
• For SpamExperts, an SPF TXT record will have the following syntax:

name.domain.com TXT v=spf1 include:spf.antispamcloud.com

• This record should be published in the DNS records section for the relevant domain.

Worth noting: To activate SPF for outgoing emails using SpamExperts if your domain previously lacked an SPF record, all you need to do is publish the aforementioned record. If your DNS already contains an SPF record, you must update it to include SpamExperts as shown below:

Previous SPF record:  v=spf1 mx -all

Modified SPF record:  v=spf1 mx include:spf.antispamcloud.com

• Save adjustments.
• Allow your DNS to process the adjustments for 72 hours.

How to Configure SPF for SpamExperts Local Cloud Users

SPF record Values

Create a TXT record with a list of all the Public IPs used for SMTP submission traffic if you are a Spam Experts Local Cloud User. For instance, if your cluster exclusively use IP 1.2.3.4/32 for outgoing traffic, a record like this may be used:

spf.yourdomain.tld = v=spf1 ip4:1.2.3.4/32 -all

SPF record for customers :

v=spf1 include:spf.yourdomain.tld -all

It is advised to create a comparable DNS hostname, but for SPF include all cluster IPs set up to send SMTP traffic to the hostname as multiple A records so that, in the event that IPs are changed or rotated, senders SPF records are not affected.

spf.yourdomain.tld > A > Primary sending IP of 1st server
spf.yourdomain.tld > A > Secondary sending IP of 1st server (if configured)
spf.yourdomain.tld > A > Primary sending IP of 2nd server
spf.yourdomain.tld > A > Secondary sending IP of 2nd server (if configured)

Add “a:spf.yourdomain.tld” to the DNS record for your sending domains if they already use SPF. If you wish to configure this (and direct all email to the Spam Experts server because they lack an SPF record), create something along these lines :v=spf1 a:spf.hostname.tld -all
