    We have a client who we relay mail for. They have their own domain. We hold
    their mail on our server until they connect over ISDN and send an ETRN.
    Their outgoing mail is also sent through our server.

    We have their domain in 'relay_domains' to allow the mail through, however
    we have had some instances of people maliciously sending mail purporting to
    be from our clients, which we then relayed.
    How can we only accept mail for this domain if it comes from their IP? (we
    allocate them a static IP)
    I thought that we could use a 'smtpd_sender_restrictions' map to limit
    senders from this domain to a single IP, but I cant work out how to do it.

    Thanks

    Steve
