I had two computers and i'm now i want to consolidate and start using one, so i dragged my mail folder from the one i'm no longer using (from the user>libraries>mail) to and external hd, because i'm going to erase it, and i wanted to move all the messages on the hd to the other computer. I think i remember doing this before so i manually dragged the messages in the same folder on the othe mac, they were all for different accounts and the messages were appropriately dropped in the correcte messages folders for the correct accounts, but the didn't show up in mail, so i restarted and nothing. The emails i dragged into the messages folders are still in my folders on the new mac, but they do not show up when i open mail.
