Thank you for your reply. I'm being driven mad by Gmail rejecting my SPF record, this while I get SPF record approvals everywhere else.
I read that having two SPF records for the same server will generate errors. Is this true? [...]
I'm not an SPF expert (I don't even use it for my domains), but I do know how to query standards documents. IETF RFC 7208 "Sender Policy Framework (SPF) for Authorizing Use of Domains in Email, Version 1" states in §3.2: "A domain name MUST NOT have multiple records that would cause an authorization check to select more than one record."

Hope that helps!
