Question: I have been using java mail to automate Gmail operations.
One of the operation is to delete mail and I use following for it -

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

```

but doing so only pushes my mails to spam folder.

I am wondering if there is a straight way to delete mail permanently instead of deleting mail from "inbox" first and then searching mails in "spam " folder and deleting them.

Answer: 
According to <http://mail.google.com/support/bin/answer.py?answer=78755>:

> 
> If you want to delete a message from all folders, move it to the [Gmail]/Trash folder.
> 
> 
> If you delete a message from [Gmail]/Spam or [Gmail]/Trash, it will be deleted permanently.

However, that page doesn't give any indication that your approach would move mail to the spam folder; and it implies that you *should* see a folder named `[Gmail]/Spam`; so maybe it doesn't apply to your situation, somehow? I think you'll just have to try its approach, and see whether it works for you!
You told that you are trying 

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

```

did you tried 
`folder.close(true);`
this will expunge all messages with DELETED flags.
