I had a hard crash on my Mac PowerBook and when I restarted, Mail came up with only my MobileMe account still available and I cannot figure out how to restore the other eight email accounts I have.
The directories in ~/Library/Mail all seem to be there. I even did an rsync of the modified .plist files from a TimeMachine backup of the directory from before the crash (unfortunately, I was on travel, so the backup is more than a week old and I'd like to try and recover from that point without having to entirely restore from TimeMachine).
I also did a fix permissions.
So my questions are where exactly is the account information for Mac Mail kept? Any thoughts of what might have caused the failure? Why does only MobileMe come up? Any other thoughts on how to fix things?
