Sender Policy Framework (SPF) is a method of fighting spam. As more time passes, this protocol will be used as one of the standard methods of fighting spam on the Internet. An SPF record is a TXT record that is part of a domain’s DNS zone file. The TXT record specifies a list of authorized host names/IP addresses that mail can originate from for a given domain name. Once this entry is placed within the DNS zone, no further configuration is necessary to take advantage of servers that incorporate SPF checking into their anti-spam systems. This SPF record is added the same way as a regular A, MX, or CNAME record.
v=spf1 mx a ip4:220.127.116.11 ~all
* Make sure the IP above has an A record set in the DNS zone
"v=spf1 a mx ~all"
“v=spf1 a mx ip4:IP.ADD.RE.SS include:mail.domain.com ~all”
domain.com. IN TXT “v=spf1 a mx ip4:IP.ADD.RE.SS include:spf.messaging.microsoft.com include:mail.domain2.com ~all”
When should I use one?
An SPF record is generally used when your company is trying to avoid people using your domain for SPAM. The thing you need to know when working with SurveyGizmo is making sure that if you do have an SPF record, that we are whitelisted in it. Whitelisting us will allow you to use your domain as the FROM field when using the SurveyGizmo application to send out email campaigns or send email actions.
What should I avoid?
If you don’t have an SPF record already in place, then we don’t recommend setting one up mid-campaign. Adding one will most likely not increase your deliverability in any way.
If you already have an SPF record, or are setting one up for other purposes, you’ll want to make sure you don’t set it to only allow SurveyGizmo. If you do, then you won’t be able to send out emails from any other servers.
If I have an SPF record, and need to whitelist SurveyGizmo, what should I use?
If you already have an SPF record set up on the domain you want to send emails from, then we recommend adding the following IP addresses to your SPF.
This will include our servers in your preferred server list. You can also use “include:sgizmo.com”, however, the IP addresses above are more practical. If you were to use “include:sgizmo.com” it would include all of our SPF records, which is excessive as we have internal SurveyGizmo IP addresses that the application doesn’t use.
How to make one
SPF – v=spf1 +a +mx +ip4:18.104.22.168 ?all
