+Summary: System.Net.Mail.SmtpClient is not doing any rfc 2047 encoding on headers
+
+Headers generated by System.Net.Mail.SmtpClient aren't being rfc2047
+encoded at all, so setting any of them (Subject, DisplayName on any
+address, ...) with non ascii characters will generate a message that
+violates rfc 2822.
+
+The deprecated System.Web.Mail.SmtpClient did at least do some simple
+encoding (though it always defaults to base64).
+
+Simple test case:
+
+System.Net.Mail.SmtpClient client = new
+System.Net.Mail.SmtpClient("localhost", 25);
+client.Send("address at example.com", "address at example.com", "Subjet with non
+ascii content áéíóú.", "body");
+
+The generated subject line will only be readable if the recipient's MUA
+guesses the encoding.
