The main difference is that if you set mail.imap.expunge_after_deletetotrue using the Config editor Thunderbird will compact the folder after it successfully copies the message to the trash folder. [1] The same thing occurs if you move a message to another folder since moving a message deletes a message and then copies it. Shift+Delete deletes the message without copying it to the trash folder, and is also supposed to compact the folder (if you have that preference set). However, some users report that Shift+Delete doesn't always compact the folder. [2] If you want Thunderbird to ask for confirmation when emptying a trash folder, set mail.imap.confirm_emptyTrashFolderDeletion to true. [edit] Remove it immediately 标志为删除，不在view中显示，执行压缩后真正删除 "Remove it immediately" doesn't actually remove the message despite its name. It just hides it from view and flags the message as deleted. That appears to be because Thunderbird doesn't support the optional UID Expunge command, which requires the server to support the optional UIDPLUS capability. It will be physically deleted when you compact the folder. [edit] Mark it as deleted  增加删除线 The main difference between "Mark it as deleted" and "Remove it immediately" is that it doesn't hide the message, and disables automatic expunging of the account (if its enabled) . It draws a line through the message in the folder listing. You can undelete the message by deleting the message again. [edit] Misc  杂项(达到20个标志为删除的消息后执行压缩) Tools -> Account Settings -> Server Settings -> Clean up ("Expunge") Inbox on Exit will compact the Inbox folder when you exit Thunderbird. If you check "Empty Trash on Exit" it will also empty and compact the Trash folder when you exit. The Penelope extension and Eudora have a mail.imap.expunge_option that provides auto-expunge like the original Eudora [3]. It was later on added to Thunderbird 3. [4] 0 means it will never occur 1 means it always occurs 2 means expunge the deleted messages when there are at least 20 messages waiting to be expunged. You can change the threshold usingmail.imap.expunge_threshold_number. Some IMAP email providers (such as Yahoo [5]) periodically remove any messages in your Trash folder, and don't let you control when this happens.
