How To SPF set to Virtualmin By Tech and Dev

Set up SPF in Virtualmin

What is SPF?

Sender Policy Framework (SPF) is an anti-spamming technique that detects email poofing and verifies the sender's IP address, allowing only specific servers (s) to be sent on behalf of a domain.

Set up SPF:

1- Make sure you have a valid host name and it's on your server's main IP.
2- To check or change your host name, go to Webmin => Networking => Network Configuration => Hostname and DNS Client.

3- Add the below to your domain records as a SPF or TXT record.
v = spf1 & nbsp; n mx ip4:xxx.xxx.xxx.xxx ~ al
where xxx.xxx.xxx.xxx is your server's main IP address.
Do this for every domain name you offered in the virtual operating system.

The flow chart below shows how SPF works:
