[ disclosure: I work for a company probably affected by this policy ] So, there's a quandary here. Email is exchanged between consenting systems operating under local rules. You're entitled to not accept email which you don't want and nobody can say otherwise. Yet email is built on cooperation and resources provided to others on the basis of that cooperation. Forcing mail to queue up on other peoples systems when it is legitimate is basically using other people's disk-space, unpaid, to implement local policy. That's abusive. You might ask for sign-off from your company's legal counsel about the matter of deliberately consuming the resources of others for purposes other than the purpose provided (storage for your policy, instead of hand-off) without notice, recompense etc. My non-lawyer understanding is that as an employee, you have a lot more protection against legal issues if you have, in writing, a sign-off from legal counsel; any issues then lay with management and the legal counsel. Push-back in this manner may cause reconsideration and it would never come to actually needing anything on paper -- carefully word the issue and you'd never even need to ask for something on paper, once legal counsel realise what's been asked for. If you go ahead with this anyway, then please make sure that this defer policy is in your ACLs *AFTER* all the checks which would normally lead to rejection -- you should still send 5xx permanent failures, allowing the remote site to discard mail or have their abuse systems get feedback and maybe filter out some of the 4xx temp-failed messages. You should be deferring *only* what would otherwise be accepted, not what would otherwise be rejected. You can do this by putting the defer ACL clause just before the final accept in the ACL.
