Mark’s page should have been listed prior to this but when I first viewed it was in its infancy and I did not see any links that I did not already have. Mark has a nice list of resources, several of which are not available here or on any other GMail resource list. He is the author of GML, a fine GMail mail import tool, and you will find many import resources in his list.

Thanks to Littles for bringing this site to my attention.
