At DataPacket, we understand the importance of safeguarding your email communication. This includes ensuring the correct implementation of Sender Policy Framework (SPF) records, a vital tool in reducing the risk of email spoofing and improving mail delivery success rates.
When configuring your SPF record, it's crucial to specify the "include" parameter. This parameter designates that mail can be sent from servers other than your primary SMTP server. In our case, the parameter would be
include:interlayer.net, which designates DataPacket's multiple SMTP servers as authorized senders for your domain.
Without the "include" statement, your SPF record might only reference your MX record, which could lead to mail delivery failures or your emails being classified as spam. This is because the SPF record might not cover all the servers that are actually sending email for your domain.
Here's how you should include the "include" statement:
And here's an example of a complete SPF record that uses the "include" statement:
v=spf1 mx include:interlayer.net ~all
This SPF record tells receiving mail servers that they should accept mail from the servers defined in your domain's MX record and any servers defined in the "interlayer.net" SPF record. The "~all" mechanism signifies that mail from any other servers should be treated as suspect.
By correctly specifying your SPF record, you're enhancing your domain's email security and improving your email deliverability. At DataPacket, we're here to ensure your web hosting experience is smooth, secure, and efficient.
