Hi Timo....

For tests i do it:

In src/lib-storage/index/maildir/maildir-mail.c


In the final of function maildir_open_mail i change the i_stream_create_fd
to this:

------- origin ------
    int fd  = -1;
.
.
.
.
.

    if (fd == -1) {
        *deleted_r = TRUE;
        return NULL;
    }

    input = i_stream_create_fd(fd, 0, TRUE);
    index_mail_set_read_buffer_size(mail, input);
    return input;

----------------------

-------- my  ------------
    int fd  = -1;
    int fd1 = -1;
    int fdp[2];
.
.
.
.
.
.
    if (fd == -1) {
        *deleted_r = TRUE;
        return NULL;
    }

    do_open(mbox, "/storage/emexis/
exemplo.com.br/messages/alex/Maildir/body_test", &fd1);
    fdp[0] = fd;
    fdp[1] = fd1;

    input = i_stream_create_concat(fdp);

    index_mail_set_read_buffer_size(mail, input);
    return input;
--------------------------
But the concat don't work.

I Try too create 2 streams and put this 2 fds in concat, not work too....

---------- my second ----------------
    int fd  = -1;
    int fd1 = -1;
    int fdp[2];
.
.
.
.
.
.
    if (fd == -1) {
        *deleted_r = TRUE;
        return NULL;
    }

    do_open(mbox, "/storage/emexis/
exemplo.com.br/messages/alex/Maildir/body_test", &fd1);
    fdp[0] = fd;
    fdp[1] = fd1;

    input = i_stream_create_fd(fd, 0, TRUE);
    input = i_stream_create_fd(fd1, 0, TRUE);
    input = i_stream_create_concat(fdp);
--------------------------------------------
