I set charset property of idSMTP component to windows-1251 and send the message.

Then I get that e-mail with properly encoded body and WRONG encoded subject.
Subject is KOI-8, body is Windows-1251.

Subject: 1 =?KOI8-R?B?6uDw8ujt7uog7vI6?=
Content-Type: multipart/mixed; charset="charset="windows-1251"";

Is it Indy issue, or SMTP server, and how work it around?
