I. Intro
Who can perform these steps: Primary administrators or administrators with Email permissions.
Sender Policy Framework (SPF) is an email authentication method that uses IP addresses to verify the identity of senders. By checking whether the sender's IP address is listed in the domain's SPF record, the receiving mail server can determine whether an email is genuine or spam, and accept or reject it accordingly.
Notes:
- The default SPF record used by Lark Mail is "v=spf1 +include:spf.onlarksuite.com -all".
- If your organization needs to send emails from other servers, the addresses of these servers must be added to the SPF record.
II. Steps
Configure an SPF record containing multiple DNS addresses
Add the required Domain Name System (DNS) addresses to the SPF record used by Lark Mail. For example, if you need to add "example.com" as a sender address, the SPF record should be configured as follows:
v=spf1 +include:spf.onlarksuite.com +include:example.com -all
Required format: v=spf1[space]+include:spf.onlarksuite.com[space]+include:example.com[space]-all
Configure an SPF record containing multiple IP addresses
Add the required IP addresses to the SPF record used by Lark Mail. For example, if you need to add "IPv4:173.194.72.103" as a sender IP address, the SPF record should be configured as follows:
v=spf1 +include:spf.onlarksuite.com +ip4:173.194.72.103 -all
Required format: v=spf1[space]+include:spf.onlarksuite.com[space]+ip4:173.194.72.103[space]-all
Configure an SPF record containing multiple IP and DNS addresses
Add the required IP and DNS addresses to the SPF record used by Lark Mail. For example, if you need to add "IPv4:173.194.72.103" and "example.com" as sender IP and DNS addresses, the SPF record should be configured as follows:
v=spf1 +include:spf.onlarksuite.com +include:example.com +ip4:173.194.72.103 -all
Required format: v=spf1[space]+include:spf.onlarksuite.com[space]+include:example.com[space]+ip4:173.194.7[space]-all
