Delphi SMTP component that supports UTF-8 or Unicode -

The Indy 10 SMTP component sent with Delphi 2009 does not support Unicode properly in the subject and body.

Does anyone know a good option, or have someone made the necessary changes in the Indy 10 to solve this issue?

I will also keep in mind that most mail servers can not properly handle Unicode in the mail subject line . I have not seen any actual figure on this, but I guess that a very healthy percentage of the mail server is still expected of the ASCII theme line because I believe RFC defines what.

(The course must be encoded to ensure the message body.)
