If they send mail from your domain, they should always send it through your
server (not their actusl ISPs), using SMTP authentication, possibly with
encryption and through different port than 25 (since many ISPs block 25).

That's what port 587 (submission), SMTP AUTH and STARTTLS are for. If your
postfix adds authentication info to authenticated mail headers, SA will
detect it and skip most of checks that hit.
