HELP!! My Apple "MAIL" app. unexpectedly quits each time I open it.

Question

My Apple "MAIL" app. unexpectedly quits each time I open it.
It will begin to load my mail, show the mailboxes and new e-mails and then all of a sudden quit.
I searched some of the Apple support and forums and have tried these things:
1. I trashed the "com.apple.mail.plist" preference file in the pref. folder.
2. I did an archieve install with Tiger OSX on my entire System Folder.
3. I erased my user>library>"mail folder"
4. I tried holding the shift key upon opening the program as suggested here but to no avail: http://discussions.apple.com/thread.jspa?threadID=479497&tstart=0
This has not resolved the problem. The program still quits every time I open it.
Pleeeeease help!!!!!!!!! DO YOU THINK I HAVE A VIRUS???

Answer 1

A few of the messages I deleted (the last 2 days) now say
"You need to take this account online in order to download it."
If this is the result of having deleted the *.emlx files manually, you're probably seeing this error message because there is still a reference to them in Envelope Index.
Is there anyway to tell Mail to re-download these
mail files and reconnect them?
If they're still on the server, yes. Choose Get Info (⌘I) from the Action menu located below the mailboxes list in the main Mail window to open the Account Info window -- type "Account Info" in the search field of Mail Help for more information on this feature. Now, choose the account that has the problem from the Account popup menu at the top of the window. Does Mail display there the messages that are missing? What type of account is this (POP, IMAP, .Mac)?
