I’ve been thinking about moving some of my older email out of a rather large Outlook PST into GMail, mainly for backup purposes. However, since this is far from a unique idea, I decided to see what others have done to solve this problem.
First I discovered Mark Lyon’s PHP-based Google GMail Loader (GML), which in addition to loading email, it can also be used as a remote to backup tool (I think there’s a 7.5M file limit imposed by Google).
