Correct.

Yes, you can, recipients_list contains the list of recipients.

Right.

Look in my sa-exim code, where I compute mailinfo (around line 918)

    for (i=0; i < recipients_count; i++)
    {
        mailinfo=string_sprintf("%s %s", mailinfo,
            recipients_list[i].address);
    }


You probably want to create a header before you feed the mail to spamc,
around line 523:
    /* Ok, we're ready for spewing the mail at spamc */
    /* First we need to get the header lines from exim, and then we can read
       the body from fd */


This actually sounds like a good idea, so I'm going to add a X-SA-Rcpt-To:
header with the list of receipients in version 2.2
