Sorting through old emails

At the Sunday Second Life genealogy discussion Clarise suggested connecting genealogy emails with families and individuals in your Genealogy Software program etc. I have been very bad when it comes to managing my email accounts :(. So I have thousands of emails in 4 accounts. Most of  these are in the inbox. I am now forwarding most mail to gmail.  I have now set up email filters at gmail to filter unwanted mail from certain addresses. I have also set up family folders, or as gmail calls them labels,  for each family plus a general genealogy folder. I plan on keeping the boxes tidy now :D.
I am now going to read through and copy them to my genealogy program notes. I have messages going back to 1999. An example of some great info I received via email,  from Ireland, with wonderful family info:
