Correct. External services that made prior arrangement with user for using
such a service, i.e. its an xSP (ISP/ASP/MSP..) service.

That is effectively the same thing as ISP email service, we just separate 
meaning of email service being provided by ISP into email receiving service
and email sending service and specify that both may involve separate 
independent arrangements and separate providers. I suspect that in 99%
of cases its still going to be the same provider, but its good to provide 
for possibility of alternative just in case.
