The latter, but although it may in general be a bad idea, (1) the other
server (surrey.ac.uk) is well set up for catching and dealing with spam etc.
(e.g. all mail sent to it is processed through messagelabs span filtering),
and (2) there is no easily accessible list of users that are known on
surrey.ac.uk, but unknown to soc.surrey.ac.uk.
