 To add a SPF record in your DNS, insert the following line in your DNS zone:
 
-    ; Check that MX is declared
+    ; MX record must be declared for SPF to work
     domain.com. IN  MX 1 mail.domain.com.
 
-    ; Add SPF record
+    ; SPF record
     domain.com. IN TXT "v=spf1 mx ~all" 
 
-This enables the Softfail mode for SPF. It is a good setting for getting started and testing everything. After verification, you might want to change your SPF record to: `v=spf1 mx -all`, to enforce the policy!
+This enables the _Softfail_ mode for SPF. You could first add this SPF record with a very low TTL.  
+_SoftFail_ is a good setting for getting started and testing, as it lets all email through, with spams tagged as such in the mailbox.
 
+After verification, you _might_ want to change your SPF record to `v=spf1 mx -all` so as to enforce the _HardFail_ policy. See https://www.spf-record.com/syntax for more details about SPF policies.
 
-Increment DNS serial and reload configuration.
+In any case, increment the SPF record's TTL to its final value.

-For whitelisting a IP-Address from the SPF test, you can create a config file(See [policyd-spf.conf](http://www.linuxcertif.com/man/5/policyd-spf.conf/)) and mount that file into `/etc/postfix-policyd-spf-python/policyd-spf.conf`
