[Dovecot] Thinderbird+delete+move to Trash folder

[Papp Tamás]

hi All,

I have a problem, which makes me headache. I can't find out, what is the 
problem.

I have a mail szerver, which works just fine as expected, TB move 
messages to trash folder after I delete it, and they are moved.

I have an other server. If I delete a message, it doesn't move to the 
Trash folder. As deleted_to_trash plugin is installed, if I only mark 
messages as deleted, they are moved to thee Trash folder and also with 
Outlook works well.


It's like when a messages is deleted from TB, the message get moved to 
the Trash folder, and it's expunged(?) at the same time. Is it possible?

Could you help me?

The system is Ubuntu 9.04 with docecot 1.2.5-0~auto+0 from 
http://xi.rename-it.nl/debian/, but builded by myself for x86_64.

Thank you,

tamas
