[Dovecot] Thunderbird and Trash folder

[Stefan Onken]

Hello,

I have my problems with the Trash folder in thunderbird. Most of the 
times (it did work, but only for a short period) Thunderbird is not 
considering the "Trash" folder (or in my case the "Papierkorb") as the 
trash folder. The symbol disappears and I am not able to delete folders. 
Deleted emails are disappearing at all.

The usual Google solutions like maildir vs. mbox doesn't help a lot, I 
am using maildir and the directory structure looks fine. I noticed that 
I have two trash folders, one with "INBOX.", one without. That may be a 
problem with Squirrelmail, because I am using both Thunderbird and 
Squirrelmail.

Any idea to solve this issue with Thunderbird ?

Thank you,
Stonki
