Gmail is very special when it comes to IMAP. Gmail uses labels, not folders, and there is simply no one-to-one mapping to IMAP. For example: putting a message in the Trash actually kind of assigns the label 'Deleted'. When labeled as such, any other label for that same message no longer applies. Be sure to understand the implications of this. Like if you think you copied a message to some IMAP folder, then actually Gmail will only have assigned an additional label to the very same message.

Now, if you've ( wrongly) set up Mail to move deleted messages to the Trash, then after 'deletion' of either of the two occurrences of that single message, the other is removed as well. Anymusic app for mac. So, if your rules move messages to specific folders on the Gmail server, then beware! When moving to a local folder on your Mac, then deleting from the Gmail server may not harm you. To get the full picture when using IMAP for Gmail, one should unfortunately at least read all of the following from Google's help: • • • (first read the general notes before clicking through to the email client of your choice; be sure not to save deleted messages to the Trash) • Finally, see, which allows you When a message is deleted from the last visible IMAP folder: Move the message to the Gmail Trash.
