How to check if Sender Privacy Framework (SPF) is setup correctly ?

Sender Privacy Framework (SPF) is a method used to prevent sender address forgery, i.e. someone to pretend someone he/she is not and send SPAM emails.

Open a terminal window and type:

$ host -t txt

You may see a message stating:
" has no TXT record", so DNS changes need some time to propagate.

Another approach could be to query the DNS server that your web site is using:

$ host -t txt

The output should be:

Using domain server:
Aliases: descriptive text "v=spf1 a mx -all"

Notes: is YOUR domain
Address: is your domain's IP address.
the record in /var/named/data/ has contains following line. IN TXT "v=spf1 a mx -all"
