[bug-mailutils] Trash folder issue?

[Chris Hall]

Hi, Sergey,

When I use 'mail' from my laptop to my server via
imap://address@hidden/RSS/The Register, I can view and delete
messages fine, and iamp4d doesn't complain.

I finally managed to see enough of the Thunderbird message to see that
it was moving the deleted message to Trash, but then it puts it back in
the original folder, with nothing in Trash.

Where is Trash supposed to be, and what file permissions does it need? 
Does it need to be initialized with the 'DO NOT DELET THIS MESSAGE'
business?

Mine is currently in $mailhomedir/Trash with mode 0660, and a file size
of 0 bytes.

Sincerely,

Chris
