Moving messages from Inbox to Local Folders does not delete the message from Inbox on POP server.
I have the "Leave messages on the server" set to "Until I delete them". Since this is a POP account - moving a message from my Inbox to a local folder should be considered equivalent to "deleting a message from my Inbox". However TB does not remove the message from the Inbox on the server. This results in accumulation of messages on the server that should not be there. They've been deleted from the client Inbox so they should be deleted from the servers Inbox, as the setting has requested.
Is there a way to correct this behaviour or does there need to be a new setting to make it do the right thing?

There is this advanced setting
mail.pop3.deleteFromServerOnMove
I did not test it, but maybe it does what you want ?

That setting is intended to provide a backup copy. You have a copy on PC, yet also want a backup on server. Your moving the email to another folder is not a signal to delete the backup on server. Thunderbird is doing exactly as designed. The solution is to change your setting for keeping backups on server.
I don't see the word "Backup" anywhere on the setting for this. It's a mail management setting. And the current behaviour is unusable. You end up with messages distributed across possibly hundreds of local folders that are also stored in your "Inbox" on the server. Unmanageable. Changing the setting is not a solution. My clients "Inbox" should reflect what is on the servers "Inbox".
Why else would a person need copies in the server inbox if they also have copy on their PC? It's a backup, that that is the traditional use. If they want what is on server to reflect the true inbox, then they should be using IMAP, not POP, considering the expectations you describe.
Apparently that option used to be called "Until I delete or move them from Inbox". Which explains why this problem didn't occur in the past. Not sure when it changed but the new behaviour is most irritating.

Wow! Looks good. I found another thread that indicates it works as desired. Thanks for pointing this out. New to me. I'll add to my list of tips.
Thanks gp. I think that's exactly what I need. They must have added that when they changed the default behaviour.
