Thanks for the attempts to help, but I've now gotten finally got Mail working, although all my incoming e-mail messages that were not archived on the server are gone (because they erase old messages from their server after a couple of weeks).
Here's what I did to get Mail working again: I called my ISP's help number, got a Mac user there, and told him I'd upgraded to Leopard and it broke Mail, and he said that was getting to be an old story; they've gotten numerous calls for help for the same reason. What he did was have me set up my mail accounts all over again, from scratch, talking me through all the settings. Even after that, we sent a lot of test e-mails that failed to get through, either to him or back to me. After all else failed, he told me to just reboot the machine and see if that did any good. It did. After rebooting. Mail was able to send and receive mail. I wonder now whether I should have just rebooted the machine immediately after the upgrade, before trying to launch anything. If I had, maybe Mail might have worked. Hindsight . . . . Anyway, I have still lost several mailboxes that I tried to import into Mail from the Library > Mail folder earlier, before I called the ISP for help. That was when I had two copies of each mailbox, an empty one that was there when Leopard's Mail first appeared, and a second one that did have messages in it. All the full mailboxes were in a mailbox/folder labeled "Imported." In trying to get rid of the empty mailboxes and replace them with the full ones, I did something wrong and lost some of the full ones. Sadly, for me, I had no recent backups of those mailboxes. My backups, on another computer, are a few months old, but they're better than nothing I guess. I lost any recent messages in them. I also asked for help with this problem in the Apple Discussion Forum for OS Leopard Mail, and got a reply from another person who had the same trouble after the upgrade, and who had this to say about it: "I had the same problem and called apple support. Here is what we did. Logged in as a guest and opened mail, new messages started coming in. Logged out of the guest account and logged in as myself. In the Library, we moved the entire Mail folder to the desktop. Opened Mail program and new messages started coming in. Then went to Import mailboxes and choose the Mail folder that I moved to desktop. After mailboxes imported, mail worked perfectly. Deleted the Mail folder on my desktop. Voila!!! Hope this solves the problem for you. You have 90 Days of phone support when you buy Leopard." Well, that fix wouldn't have worked for me, because I couldn't have logged in as a guest--your Mac has to be on a network to do that, doesn't it? At least in Pogue's OS-X book, the topic of logging in as a guest is in the networking chapter. I couldn't figure out any way to do it on my Mac, which is not on a network. Anyway, trying to look on the bright side, I guess all's well that ends without complete destruction of all your data. This was only partial destruction of my mailbox collection. Now to play around with Leopard and find out what else might be broken. This is a disappointing upgrade, to say the least.
