It is hard to trash messages from gmail..

I found out that it is very hard to remove a message from gmail using the LDAP api. At first, I just tried doing the following:

((Message)message).setFlag(Flags.Flag.DELETED, true);

This should work for common ldap accounts, but it doesn't work properly in gmail. It just removes the message from the "folder", which is actually mapped as a gmail label. The message will remain under "All messages". Next, I found that I should move the message to the trash folder:

Folder skypeFolder = mailStore.getFolder("Skype-Chats");
Folder trash =  mailStore.getFolder("[Gmail]/Trash");

Message[] messagesToRemove = new Message[]{messageToRemove};
skypeFolder.copyMessages(messagesToRemove, trash);
// and just to make sure
mimeMessage.setFlag(Flags.Flag.DELETED, true);

Well, it did work... kinda. A problem still remained: if you send a new message with the same sender and subject, the "deleted" message gets resurrected.

I couldn't figure out how to remove it permanently. I got around the problem changing the subject, when need...
