398854 - mail.pop3.deleteFromServerOnMove is erratic

Status: RESOLVED DUPLICATE of bug 333344

(Thunderbird :: General, defect)

Description

[Dan Mitchell]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.7) Gecko/20070914 Firefox/2.0.0.7
Build Identifier: version 2.0.0.6 (20070728)

I wanted to preserve the old behavior where moving messages out of a pop3 inbox removed them from the server (see, for instance, bug 378474).

 I asked in the forums, and was told to set mail.pop3.deleteFromServerOnMove -- I did that, and it partly works. I emptied my mailbox out yesterday; got mail this morning, and only some of the messages that were processed by rules or the junk mail filter were removed from the server. Some of the messages remained.

 What's more, when I move messages manually, they stay in the inbox. (and are still there after closing and reopening Thunderbird, and disconnecting/reconnecting with webmail/telnet).

Reproducible: Always

Steps to Reproduce:
 For the "fails to move":

1. Set mail.pop3.deleteFromServerOnMove to true.
2. Move a message from the inbox to an offline folder. (or have a message which the junk mail filter moves from the inbox to the offline junk folder)
3. Close Thunderbird
4. Connect to mail server with (say) telnet
5. Verify that the message has not been deleted from the server.
Actual Results:  
Step 5: the message is still on the server.

Expected Results:  
I'd expect the message to be gone from the inbox.

Mail server is Rockliffe Mailsite POP3 server 7.0.6.1.

 (apologies for filing this as "general", but there's no component for "mail server connectivity issues")

Note: Thunderbird 1.5.0.13 works fine -- moving messages _does_ remove them from the inbox, so this functionality got broken somewhere in the move to v2.

In the steps to repro, did you also receive mail once as step 6? I think the messages are not deleted immediately, but on next fetch mail.

Yes, Thunderbird only deletes mail while checking for new mail.  Since that's not what people expect, there's another bug to change that behavior.
