You will, at a minimum, need to provide the message source of a 
message that is not being displayed correctly.

Hy,

I am using horde imp 1.2.3, in centOs5.4. I am having a problem to 
send a message and redirect the message with encoded ISO-8859-1. On 
Gmail and Hotmail that's works but on the  others webmails they appear 
not correct encoded.
