The SPF validation may fail for a few reasons and you might likely encounter the error “**SPF record not found**”. Here are some steps to troubleshoot and resolve the issue: ### 1\. **Multiple SPF Records** If your domain has multiple SPF records, they need to be combined into a single entry. For example, if your domain’s SPF records are `include:abc.com` and `include:def.com`, you will also need to include the Zoho Books SPF record, which can be copied from the **Sender Email Preference** page in _Zoho Books_. The combined SPF record should look like this: ``` v=spf1 include:abc.com include:def.com include:sender.zoho-books.com ~all ``` **Pro Tip:** For organisations created in the Indian Data Centre, the Zoho Books SPF record is `include:sender.zoho-books.in`. If you have multiple SPF records, delete the existing records and combine them into a single entry. ### 2\. **Incorrect Type or Host Specification** Ensure that the **Type** is set to _TXT_ and the **Host** is specified as **@**. These settings are important for proper SPF validation. **Note:** The SPF records must be specified against the **TXT Value**. ### 3\. **Incorrect Symbol before “all”** Make sure that the symbol `~` is placed before “all” in the SPF record. Sometimes, it may mistakenly be entered as a hyphen `-`, which causes the SPF validation to fail. ### 4\. **DNS Lookups** An SPF record can only have up to 10 DNS lookups. If your SPF record exceeds this limit, the validation will fail. * * *
