A note about mail delivery: a message sent from an external user at another organisation to a Birkbeck email address (@bbk.ac.uk) will hit the Messagelabs servers where it is checked first, and if accepted will pass to the Birkbeck mail gateways (where it will be checked again), and then directed to the relevant email system. A message sent to Birkbeck gmail (@mail.bbk.ac.uk) from the same sender will route directly to gmail. A message sent from a Birkbeck Exchange user to another Exchange user will remain with Exchange (does not pass through the mail gateways). A small proportion of messages will be counted twice, particularly where distribution lists are used.
