No, a domain can only have one SPF record. Having multiple SPF records will cause the SPF check to fail. If you need to include multiple mechanisms, you should combine them into a single SPF record.
If you encounter an error, first verify that the domain name is spelled correctly. Check if the domain has a valid SPF record in its DNS settings. Common issues include missing SPF records, syntax errors, or DNS propagation delays.
SPF records have a limit of 10 DNS lookups per check. If your SPF record includes too many include mechanisms or redirects, it may exceed this limit and cause the SPF check to fail. You should optimize your SPF record to stay within this limit.
