InternetAddress not being encoded

Question

Hello all!
From a HTML-form I get this Input:
"&#1044;&#1072;&#1088;&#1100;&#1103; &#1040;&#1083;&#1072;&#1084;&#1087;&#1080;&#1077;&#1074;&#1072;" <darja@localhost>
Now on the server-side I do:
inetAddresses[ii] = new InternetAddress(actAddress);
debug:
actAddress= ""&#1044;&#1072;&#1088;&#1100;&#1103; &#1040;&#1083;&#1072;&#1084;&#1087;&#1080;&#1077;&#1074;&#1072;" <darja@localhost>"
Now I do:
mm.setRecipients(Message.RecipientType.TO, inetAddresses);
debug:
mm= MimeMessage (id=123)
Now the MimeMessage has this Header:
[13]= InternetHeaders$InternetHeader (id=176)
     line= "To: "&#1044;&#1072;&#1088;&#1100;&#1103; &#1040;&#1083;&#1072;&#1084;&#1087;&#1080;&#1077;&#1074;&#1072;" <darja@localhost>"
     name= "To"
     value= ""
Isn't this a bug? Shoudn't javamail (MimeMessage or InternetAddress) encode the Adress to:
=?koi8-r?Q?=E4=C1=D2=D8=D1_=E1=CC=C1=CD=D0=C9=C5=D7=C1?= <darja@localhost>
or something like that???
I would expect a debug-output like this:
[13]= InternetHeaders$InternetHeader (id=176)
     line= "To: =?koi8-r?Q?=E4=C1=D2=D8=D1_=E1=CC=C1=CD=D0=C9=C5=D7=C1?= <darja@localhost>"
     name= "To"
     value= ""
If I set a subject via "setSubject(myString)" then MimeMessage does the encoding for me.
I think this is not consistent...
Javamail shouldn't let me take care of encoding eMail-Adresses...
Best regards

Nice workaround, but I still think it is not
consistent, that in one case (setSubject) javamail
does the encoding for me but not in the other one...
But this is a matter of the API-specification.JavaMail does do the encoding if you use the constructor
that allows you to specify the personal name and email
address separately. The only time it expects to parse an
address in the form you gave it is when it appears in a
mail message, in which case it should be properly formatted.
Certainly no one is expected to type in an address in that
form.
Adding the ability to parse such an address might be a
reasonable addition, but I don't know how often it's likely to
be used. Certainly in the last 8 years this has never come up.
What about IDN-Domains? I didn't find anything about
it in the API-Docs and Google gives me just 5
(useless) results for "idn javamail
InternetAddress".
What if the input comming from a webform is "Martin
M�ller <martin@m�ller.com>"? I can see that the
resulting to-line is:
[13]= InternetHeaders$InternetHeader (id=75)
     line= "To: "Martin M�ller" <martin@m�ller.com>"
     name= "To"
     value= ""
How do I "xn-encode" this IDN-address (with
javamail-"standard accessory")?That's a good question. I don't know anything about IDN
support in Java in general, and certainly JavaMail doesn't
have any specific support for it.
