I had installed the Lion on my iMac, but the machine was very slow and some software were hanging and quitting, and I decided to downgrade to Leopard. I have a backups of all my documents, but the Mail backup is in Time Machine disk. I cannot retrieve the Time Machine in Leopard because they are not compatible. I have manual access to all files in the Time Machine disk. I'd like to know which Mail files I have to copy to my system drive to get back my accounts, all my emails and folders that I created within Mail.
I appreciate any help.
