Mail

For what type of account is this account's Inbox mailbox - .Mac, IMAP or POP?

And if an IMAP account, is this an AOL account?

OK and I have more questions.

Did you upgrade to Tiger from Jaguar or Panther on this Mac and if so, how long ago?

Are you accessing a single account with Mail?

Hi.

I have exactly the same problem. Bought my Macbook in June last year and noticed this problem in November... it seems whenever mail gets to about two months old or so, it simply disappears, no matter what folder it is in. Although all mail prior to September 2007 is still there.

The Apple guys scratched their heads and simply gave up. If you have any idea's - would be appreciated. No settings are there to delete etc. Also downloading from a POP server.

Did the Apple guys have you target Mail's Envelope Index file which stores an index of all mailboxes and messages within?

If not, try the following:

Quit Mail first and using the Finder go to Home > Library > Mail. Copy the Mail folder and place the copy on the Desktop for backup purposes.

Using the Finder, go to Home > Library > Mail > Envelope Index. Delete the Envelope Index file and empty the Trash.

Launch Mail and you will be prompted to import mailboxes. Select OK and all this process to complete. This isn't really importing anything but replacing the deleted Envelope Index file and reindexing all mailboxes and messages.

Any difference?

Your friend's router and server had/has no effect on this.

Using the Finder go to Home > Library > Mail > this POP account named folder (named by the user name and incoming mail server for the account) > INBOX.mbox.

List all file and folder names available within the INBOX.mbox folder.

There are some left over mbox package files from the previous Mail.app version which are not needed by Tiger Mail but are not deleted after the conversion process is completed and can sometimes cause problems.

Quit Mail first and using the Finder go to Home > Library > Mail > this POP account named folder > INBOX.mbox.

Copy the INBOX.mbox folder and place the copy on the Desktop for backup purposes.

Within the original INBOX.mbox folder within the account named folder, delete all files and folders except for the Messages folder and the Info.plist file and empty the Trash.

Launch Mail and select the account's Inbox mailbox in the mailboxes drawer and use the Rebuild Mailbox function on this mailbox.

You're welcome.

If this recovered the missing messages in the account's Inbox mailbox, you need to do the same for the other account mailboxes within the account named folder - Drafts.mbox, Sent Messages.mbox, Deleted Messages.mbox and Junk.mbox.

This should resolve the problem and if not, Tiger Mail has an Envelope Index file within the Mail folder that stores an index of all mailboxes and messages within which can sometimes become corrupt although I haven't experienced this.
