Fw: [imp] ask help about imp decoding problem

[Zhang Bo]

Hi, Michael,

Where should I hack the code of horde-HEAD or imp-HEAD to 
let the not-standard emails display chinese correctly? And how ? Can you give me 
some clue?

I think imp's mailbox.php should one, but there must be a lot of others should 
be hacked.

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
I know what you mean, but there are so many not-standard mail server which 
send not standard emails in China and other countries.
