The Convio Client DNS Checker located here:

http://events.convio.com/cgi-bin/email_dns_check.cgi

currently checks for:

outboundmail.convio.net

But doesn't accept:

outboundmail.blackbaud.net

as an SPF record. If you do an SPF record lookup for outboundmail.blackbaud.net, it includes the SPF for outboundmail.convio.net and blackbaudhosting.net. Since outboundmail.blackbaud.net includes the Convio SPF record, I'm requesting that the Convio Client DNS Checker check for EITHER the Convio or Blackbaud SPF record. That way, LO only customers can use the Convio SPF and customers that use LO and Blackbaud can use the Blackbaud SPF rather than forcing both the Convio and Blackbaud SPF records to be included. Although this doesn't cause a loop in the SPF record lookup, it's very "messy".
