Those are source routed relays.
Mailshield can protect you from such attacks.

See the Q article 304897, apparently this is a false reading, since the mail gets a DNR instead.

The problem as I understand it is that it doesn't actually relay but it forwards to another server from ours. And some blacklists now list you if this is the case. So There is no way to enable people outside our domain to check pop or imap mail without a static ip. This is my limited understanding anyway.
