I think the problem may be that you are deleting the downloaded messages in TB, but you have set the account to not delete from the server until you do so, i.e. by deleting them via the webmail access. If you don't delete them that way, they seem to be downloaded again - although the fact they do suggests a corrupted popstate.dat file. With POP accounts, a message deleted in TB is not automatically deleted from the server, whereas with IMAP accounts, it is.

"With POP accounts, a message deleted in TB is not automatically deleted from the server"

But the setting for my account (see image from my original post) indicate to delete from the server when I delete from Inbox, don't they?

Can I get TB to rebuild the popstate.dat file?

Thanks.

The setting is : 'Leave messages on server until I delete them'. It doesn't imply that deleting them from the TB Inbox deletes them from the server. But if you uncheck 'Leave messages on server', messages are removed from the server when they are downloaded to TB. Or, if you enable the setting, messages are only deleted from the server when you access the account via webmail (assuming you don't have the account set up as IMAP on another computer).

If you delete popstate.dat (TB must be closed), it will be recreated automatically, but all messages will be downloaded the first time you connect:

I am using the beta version of TB, and see the setting 'Leave message on server', with subsettings of 'For at most nn days' and 'Until I delete them'.

I have all three checked (with days set at 14). Starting two weeks after I created my account, whenever I 'Get Messages', I get an apparent time out after a minute or two with this error and no new messages downloaded:

'Error with account xxxx@frontier.com. The DELE command did not succeed. Error marking a message as deleted. Mail server pop.mail.yahoo.com responded: Too many requests.'

My guess is that 10K plus emails in the yahoo mail inbox may be exceed some limit of theirs? Or is it more general? Is there some way that TB could recover from that and continue to download new emails? Or perhaps send DELE requests in smaller batches (inferring from the error message that TB be sending a delete request for each of 10K+ emails).

I had changed my account settings not to delete messages on the server, but it didn't change the contents of the popstate.dat file, so TB continued to communicate to the server to delete messages, and the server kept saying that multiplied thousands was too many.

I followed the instruction at http://kb.mozillazine.org/Popstate.dat to edit the popstate.dat file so that the messages were marked to be kept instead of deleted.

That permitted new mail to be retrieved.

I suppose this would be a bug that the entries in popstate.dat are not getting changed when the setting get changed?

It's hard to say if there's an inherent bug, or the popstate file was corrupted, or the Yahoo POP service is unreliable (many reports of Yahoo problems).

If you wish to keep messages on the server, perhaps an IMAP setup is preferable, besides offering other advantages over POP.
