See bug 33943, supposed to be FIXED back in 2000. Still not working as far as I can tell.

Did you do GetMsg() after deleting the msg locally, that will delete it on the server.

I've been seeing this from back around 0.9.5 (??) right through to 1.1. I'm not sure if it ALWAYS happens, or only sometimes, but it certainly does happen. I only notice it because I occasionally do sanity checks on my pop accounts with a thin pop client. FWIW, I see it with both sendmail and qmail.

Seems to delete messages if you do a getmsg after deleting messages locally, but that doesn't seem like a true solution - more of a work around.

Updating and confirming bug. To reproduce: 1) Set server for [x] Leave messages on server [x] Until I delete or move them from Inbox 2) Retrieve new messages 3) Delete one or more 4) Check (however you can do this) whether messages are still on server 5) Get New Messages on server 6) Check again whether messages are still on server Actual results: Message(s) not deleted from server until after step 5. Expected results: Message(s) deleted when the Delete takes place I reproduced these results using Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7b) Gecko/20040324 I have shell access to the system that runs the mail server and used fetchmail to confirm whether the messages had been deleted. I think that most POP mail accounts are set up to check mail regularly, so the actual server deletion occurs automatically, if not immediately. At any rate, using Get New Messages is a workaround, so this is a minor bug (maybe even an enhancement). Note that the mechanism for performing this deletion is to maintain a list of kept-on-server messages in popstate.dat; when a message is deleted by the user, its entry in that file is marked; and then at the next POP update, those marked messages are deleted. This keeps the traffic to a manageable level.

Immediate deletion would make it necessary to connect to the server, log in, delete and disconnect. You want this for each message? POP isn't made for this type of use. I could live with the proposal of bug 239133. And we could modify the help and the UI to make it more clear, another server connect is needed to sync the local delete. But I'm very opposed to immediate sync.

Christian, no, I wasn't implying that it should be fixed. Mostly I'm trying to close out several apparent dupes; this bug appears to be the earliest, and the behavior described does in fact exist. I won't mind if this is WONTFIX'd, just so we have a reference bug to dupe the complaint to.

I like the when exited idea, but I also believe that at timed intervals (1 minute?) that we should reconnect to the POP server to remove messages IF there are existing messages to remove. We also need to make sure that when mailnews crashes (god forbid!) or the system crashes (god forbid!) before its gotten a chance to delete from the server, that they'll be deleted upon restart. Otherwise, they'll be a pile of messages building up on the server that SHOULD have been deleted (and it'd be a matter of time before people complained and filed a bug). That means there should probably be some hidden "deleted" folder or data structure that queues messages for deletion.

Brian, as Mike already stated in comment #6, we keep the state of the messages in the popstate.dat. There's no need of any hidden folder or other things to be introduced.

So if it crashes, and you re-open the mail client and close it, they will then be deleted?

i use thunderbird 0.8 on my notebook and my pc. on the notebook i have checked the "delete message on server when deleted locally or moved from inbox". but this feature doesn't work. on the notebook i get all the deleted mails again and again. on the pc i get them to - there i have set "automatically delete from server". there is a small problem with delete from server, as thunderbird needs another connect to the inbox to perform the delete. with only a modem dial-up i maybe don't want thunderbird to this automatically. it should do this when i hit "get messages", it first performs the delete and then gets the other new mails. in this case a small icon in the statusbar could indicate that there are mails to be deleteted... markus

wontfix is suggested in comment 8 - does this make sense?

I think so. ->WONTFIX
