The customer in question used an ESP to send marketing emails.
That ESP told him what host to include in his SPF record.
Probably some years later, that ESP changed domain and that include
became invalid.
Anyone took care to alert them about that error?
RFC 6652 provides for setting ra= and rr= tags, which are themselves flagged as
errors by most SPF checking sites...
