Don't fall for bad advice
The second most common SPF error made by organizations is publishing multiple SPF records for a single domain. This may be in part due to bad advice offered by various email service providers about setting up SPF records. People are sometimes told to create a new SPF record without anyone bothering to ask whether another functioning SPF record is already in place. Following such advice often leads to multiple records being created:"v=spf1 include:_spf.google.com ~all""v=spf1 include:servers.mcsv.net ?all""v=spf1 mx a include:getresponse.com -all"When multiple SPF records are found, all SPF authentication will fail.
