JavaMail question.

[guiding5]

Hello, mysterious ALL.

I need an advice on implementation of S/MIME and PGP/MIME using
JavaMail API.

The task is to encrypt messages using inline calls for
openssl/openPGP/gnuPG (Linux).
Its easy to retrieve message's content from JavaMail objects, but
I'm facing a problem of injecting encrypted messages back. Suddenly
JavaMail API is looking too bulky and way to overkill to use. Looks
like I need to implement a lot of classes to simply insert "ready"
content into the message.

Here the question:
Is there a way to simply set content type and add headers to the
message?
Is there a way to wrap MimePart in something with easy access to its
content? (I'd like to have something like setContentType(),
setContent(String/File), addHeader(String).

P.S. Looking into different implementations of SMIME/PGP didn't
really help; most of the implementations are way too bulky.

Thanks in advance,
Best regards, Guiding5.

A couple quick things:

1) A while back I fixed a few bugs for the protomatter project at
sourceforge in their MailLog packages - the point being there is a
some support classes for a simple mailer there (non-javaMail) that
supports MIME. It has some methods like:

MailMessage m = new MailMessage();
m.setTo(to);
m.setFromAddress(fromAddress);
m.setFromName(fromName);
m.setCC(cc);
m.setBCC(bcc);
m.setSubject(subjectFormat.formatMessageSubject(message));

if (html)
{
MIMEMessage container = new MIMEMessage();
MIMEAttachment a = new MIMEAttachment("text/html", "message body",
b.toString());
container.addAttachment(a);
m.setBody(container);
}

You might be able to find there what you are after.

2) Encryption of email in Java is most often done with the
javax.crypto.* interfaces usually with the provider being from Bouncy
Castle.

1) Going to try the protomatter's classes, seems like its much simplier
implementation.

2) javax.crypto.* provides interface for encryption providers and is
not what i looking for.

Thanks for the help !
