Mail reset to day one.
Couple days ago I noticed the "you have mail" sound I've been using for years had reset to default all by itself. Then started noticing other things that had changed from the way they've always been set. Everything else was working normal so i went on for a couple days cause i was too busy to deal with it. Then when firefox started lagging & getting glychy, I started closing windows to quit and restart when mail quit all by itself. I restarted the computer and when it started back up, mail opened on it's own and started trying to send out three years worth of Calander reminders. It couldn't send anything because all of my accounts and settings were GONE. It was like I was opening mail on a new computer for the first time and it was using a me.com account I must have set up long ago and never used.
Restarting, Permissions, all the usual and nothing changed. I look in my library folder under Mail and the accounts folders are still there but Mail isn't recognizing them.
1) Most importantly, any idea how I get my old Mail back?
2) What the @#T% happened?
My machine is a pre intel (2005 ish) G5 desktop, dual 1.8Ghz PPc running 10.5.8
Everything else is still working fine (for a dog old computer...)
