Lotus Notes Java API. Mail forwarding

Question

I would like to forward emails from my Lotus Notes inbox to my gmail account.

Lotus Notes rules and agents are disabled on our server, so I developed external application for that. I am using document.send method and mail successfully arrives to my gmail box. The only problem is that often the email also duplicated in my Lotus Notes inbox. I just found that the reason of that is "CC" and "BCC" fields, which I don't clean up, however, I am looking for the way to forward email as it is - which means keep original CC and BCC and TO fields - exactly on the same way as it is done by forwarding agent.

I am using "IBM Notes 9" on Windows 7 64 bit.

I've prepared a code sample that demonstrates what I am doing.

package com.example;

import lotus.domino.*;

public class TestMailForwarder {
    public static void main(String[] args) throws NotesException {
        NotesThread.sinitThread();
        try {
            Session notesSession = NotesFactory.createSession(
                    (String) null, (String) null, Consts.NOTES_PASSWORD);
            DbDirectory dir = notesSession.getDbDirectory(Consts.NOTES_SERVER);
            Database mailDb = dir.openDatabaseByReplicaID(Consts.MAILDB_REPLICA_ID);
            forwardAllEmails(mailDb);
        } finally {
            NotesThread.stermThread();
        }
    }

    private static void forwardAllEmails(Database mailDb) throws NotesException {
        View inbox = mailDb.getView("$Inbox");
        //noinspection LoopStatementThatDoesntLoop
        for (Document document = inbox.getFirstDocument(); 
                 null != document; 
                 document = inbox.getNextDocument(document)) {
            document.send(Consts.GMAIL_ADDRESS);
            break;
        }
    }
}

If you are unable to mail forward in the client, your admin may have intentionally disabled it. So coding a workaround may violate your company policy. Check with your admin. — Simon O'Doherty
You can't do a transparent forward with code running at the client level. Pure SMTP systems do it by preserving the RFC-822 header content while altering the RFC-821 RCPT TO data. Domino does not give client-level code independent control over these. It just uses the SendTo, CopyTo, and BlindCopyTo items. (There are some tricks that mail management and archiving vendors play in order to do things like this, but they require special changes to the Domino server's router configuration, and software on the other end as well. — Richard Schwartz
Thank you Richard. If you would put it as an answer, I would mark it as complete answer, indeed. Could I implement it with Java Mail API, so I will forward directly to gmail without Notes Server? — Moisei
Done! And I addressed the Java Mail API question there as well. :-) — Richard Schwartz

Instead of trying to send the messages to your GMail, why not upload them using Gmail's IMAP interface. You would require to get the message as MIME content - which probably they are already for external incoming eMails and then push them to GMail. I don't have a ready code sample, just one for the opposite pulling GMail into Notes, but you should be able to use that as a starting point.

A code sample for the MIME conversion is in an IBM Technote.

Hope that helps
