Our email volume is following a strange curve. The following numbers come from a week in mid-February (specifically the 11th-17th) for the last four years:
messages GB 2003 1 143 641 30.97 2004 2 480 215 62.11 2005 2 199 303 117.86 2006 2 925 334 162.70Why the drop in message count in 2005? Architectural changes to our email systems meant that fewer messages were going through ppswitch more than once; this year that has increased again because of the unbundling of the mailinglist system. It may also be a result in the changes of behaviour of email viruses (which contribute to the count).
