Ok, sorry.
it is my fault with my english :)
I sum up my wish (or rather this of my users).

Here a simple use case :
They receive a lot of spams and only use iPhone or iPad as devices.
To delete this spams, they select all messages and delete them.
Then, they go in the Deleted Folder and they want to expunge all  
messages => this is not possible...

With one of your explanations, one solution would be to not configure  
any Trash Folder in IMP. But the problem will be the same due to the  
iOS bug...

Do you have a workaround for this issue ?

(I hope I'm clear in my sentence this time :))

PS: But I repeat that this problem does not exist with an Microsoft  
Exchange Server...
