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 Zix

You must include Zix transmitting domains or IP addresses in your SPF record if you wish to integrate ZixGateway with your current Nimbus Logic configuration. You can either include:

A:zixvpm01.datbusiness.com A:zixvpm02.datbusiness.com

or

ip4:66.165.128.0/19 ip4:69.89.224.0/20 

In the event that your domain already contains an SPF record, for instance:

Previous SPF record: v=spf1 include:spf.domain.com -all

Modified SPF record: v=spf1 include:spf.domain.com A:zixvpm01.datbusiness.com A:zixvpm02.datbusiness.com -all

Worth noting: Refrain from adding more than one SPF record for a single domain.
