The problem remains in Ingo 3.1.1. The problem is very simple - when  
adding new rule, which uses not (yet) existing folder, the folder name  
is not encoded in utf7imap.

e.g. I want to add new rule, which move emails to folder "ab?". I've  
found this in html after entering new mailbox name.
<input id="actionvalue_new" name="actionvalue_new" type="hidden" value="ab?">
but it should be:
<input id="actionvalue_new" name="actionvalue_new" type="hidden"  
value="ab&AQ0-">

All existing mailboxes, listed in the dropdown (id="actionvalue"), are  
encoded in utf7imap.

So imho there is two options here:
1. Encode mailbox name with javascript right before setting it to  
actionvalue_new field.
2. Before saving rule, check weather the mailbox exists. If it  
doesn't, convert mailbox name from utf8 to utf7imap before performing  
any action further.
