Indy SMTP & SMTP Server


Has anyone tried SMTP and SMTP server with non-ascii encoding, for example Japanese?
What I want to do is forward received message to a different address. So, onReceivedMessageParsed event, I just connect to my mail server with SMTP, change the recepient address of the received message to the address I want to forward the message to and send.
Well, it's working fine except for the encoding.
The content of the forwarded mail will not be readable (junk) with many question marks.

Is there any way to work around this?
