No plans to support enforcing at proxy level. One problem here is that there are no guarantees that the connections even end up in the same proxies, although I guess if your load balancer does IP stickiness that could work well enough.
With or without a load balancer in front of the proxies, it's still very manageable. Even without a load balancer, if you have say proxy_mail_max_userip_connections=n and m proxies, the maximum number of connections that can hit the backend at any time for an user is n*m. Would this help me to better manage the resources? Think it would. Is there a business case for the feature? For us it is, we're periodically getting hammered by iOS devices that try to open 300+ simultaneous IMAP connections for a single user from the same IP, while the average hovers usually below 50 for the busier mailboxes with many folders.
