Are SPF records still used?
Thus, the SPF record is indeed deprecated, but providing an SPF policy in a TXT record is still highly recommended, even if your domain doesn’t actually handle email (in which case you should define a policy of v=spf1 -ALL ).
What happens if SPF record is wrong?
Sender Policy Framework (SPF) records help ensure that only selected servers can send emails on behalf of a domain and thus regulate sender address forgery. But an SPF validation error might mean that emails end up in spam despite them being legitimate ones.
Should I include MX in SPF?
If this mechanism isn’t in your SPF record, the default value is the MX records of the domain where the SPF record is used. Specifies that all incoming messages match. We recommend you always include this mechanism in your SPF record.
What is an SPF violation?
What Does SPF Validation Failed Mean? An SPF Validation error can occur when the Sender Policy Framework (SPF) validation for a sender’s domain does not succeed. Email admins should ensure that SPF records for their domain at the domain registrar are set up correctly to prevent such issues.
What happens without SPF?
Long periods of continued exposure to the sun without use of sunscreen increases your risks of developing skin cancer, gives rise to premature skin aging, causes skin discolorations, and makes your skin an easy victim of the harmful rays.
Why SPF record is not enough?
SPF records have a DNS lookup limit
This means that if your organization uses multiple third party vendors who send emails through your domain, the SPF record can end up overshooting that limit. Unless properly optimized (which isn’t easy to do yourself), SPF records will have a very restrictive limit.
How do I bypass my SPF limit?
How can I avoid SPF failures if I exceeded the DNS lookup limit?
- Remove unnecessary “include” statements.
- Use ip4 and ip6 mechanisms.
- Remove mechanisms that resolve to the same domain.
- Remove “ptr” mechanisms.
- Remove references to invalid and unused domains.
- Use a flattened SPF record.
How do I bypass the SPF record limit?
The number of SPF lookups can be reduced by:
- Cleaning up your record: Sometimes there are duplicate mechanisms in the record (for instance an MX record to Google Apps and an include from Google SPF)
- Use subdomains for specific email flows.
- Check if you’re using the correct included domains.
- Use SPF macros (advanced)
How do you clean up SPF records?
Optimizing your SPF Record
Remove obsolete email sources from your DNS. Use IP4/IP6 mechanisms instead of A and MX. Keep your number of INCLUDE mechanisms as low as possible and avoid nested includes. Do not publish more than one SPF record for the same domain in your DNS.
What is the difference between MX record and SPF record?
The MX record contains the DNS information for the mail server. As for which will act as the actual mail server, that depends on how you have things set up, and if you have to migrate mailboxes. An SPF record is basically just a TXT DNS record.
How do you fix an SPF problem?
Check the servers and services in your SPF record. Follow the steps in Check if you have an existing SPF record. Make sure all servers and senders that currently send email for your domain are included in your SPF record. Update your SPF record with any new sender information.
How do you fix SPF problems?
Steps to Fix SPF Validation Error
- Use valid sender.
- Domain owners must verify that their emails come from a legitimate source.
- The domain and mail record both link to the appropriate server.
- The domain’s SPF records are accurate.
- The domain used in the “from” field is accurate.
- Correct the sender SPF record.
Can I skip SPF?
A simple step of not skipping your sunscreen can go a long way in protecting your skin. Make sure to carry it with you at all times so you can reapply when necessary.

How do I find my SPF record?
Answer
- Open Command prompt (Start > Run > cmd)
- Type “nslookup -type=txt” a space, and then the domain/host name.
- If an SPF record exists, the result would be similar to:
- If there are no results or if there is no “v=spf1” property, then there is a problem retrieving the record for the domain, or one does not exist.
What do I do if my SPF record is too long?
Here are some common ways to optimize your SPF record character space:
- Remove mechanisms that resolve to the same domain. Remove any mechanisms from your SPF record that resolve to the same domain.
- Avoid ptr mechanisms.
- Remove legacy partner and vendor domains.
- Check the address range.
- Create an SPF specific subdomain.
How do I know if my SPF record is correct?
How to validate your SPF record
- Go to the SPF Checker. Go to the SPF checker of DMARC Analyzer.
- Validate your SPF record. Check the ‘I am not a robot’ checkmark and click ‘validate DNS’
Is SPF 100 too much?
Should you use SPF 100? Experts unequivocally say no. “The benefit is that it affords us about 1 percent more coverage from the UVB burning rays than an SPF of 50,” says Ciraldo. “But the risk is not worth it.”
Does SPF over 30 make a difference?
Spencer, MD. “It is logical for someone to think that an SPF of 30 is twice as good as an SPF of 15 and so on. But that is not how it works.” According to Spencer, an SPF 15 product blocks about 94% of UVB rays; an SPF 30 product blocks 97% of UVB rays; and an SPF 45 product blocks about 98% of rays.
Can you have 2 SPF records?
Don’t use multiple SPF records!
A domain name MUST NOT have multiple records that would cause an authorization check to select more than one record. The rule of thumb: multiple SPF records will fail the SPF authentication.
Is there a limit to SPF records?
Sender Policy Framework (SPF) specification comes with a limit of only 10 DNS SPF lookups per SPF record. If you are a domain owner and planning to add an SPF record to the DNS database, ensure that this limit is not exceeded, or else your SPF record check will fail.
Where do I update my SPF record?
Edit an SPF record
- Sign in to your GoDaddy Domain Control Center. (Need help logging in?
- Select your domain to access the Domain Settings page.
- Select Manage DNS to access your zone file.
- Select Edit next to the TXT (SPF) record you’re editing.
- Edit the details for your SPF record:
- Select Save to complete your changes.
What should my SPF record be?
Validity recommends an -all as it is the most secure record. SPF records cannot be over 255 characters in length and cannot include more than ten include statements, also known as “lookups.” Here’s an example of what your record might look like: v=spf1 ip4:1.2. 3.4 ip4:2.3.
What causes an SPF failure?
SPF authentication failures can happen due to the following reasons: The receiving MTA fails to find an SPF record published in your DNS. You have multiple SPF records published in your DNS for the same domain. Your ESPs have changed or added to their IP addresses which have not been updated on your SPF record.
Why did SPF cause my mail to be rejected?
If a message of yours gets blocked due to SPF, this is because (1) your domain has declared an SPF policy that forbids you to send through the mail server through which you sent the message, and (2) the recipient’s mail server detected this and blocked the message.
