I would like to allow an email service to be a valid sender for my domain. This service has dedicated a single IP for my account. 

Instead of:

```
v=spf1 ip4:1.2.3.4 -all

```

Will the following behave the same assuming I have a host record corresponding to the IP address?

```
v=spf1 include:service.domain.com -all

```

\**edited to correct -all syntax*
