IPM Settlement Check??

I missed out on a hefty payment from the lithium ion battery antitrust settlement, "Reverse the Charge", apparently because they chose to distribute payments by email instead of USPS. In the many years between sign-up and distribution, I had changed primary email providers, still getting the legacy email via POP protocol, but going to its website to check their spam trap only infrequently. As best I can tell, the final settlement notices and e-payment were sent during a time when the provider's spam filter was very aggressive and trapping almost everything, before I noticed the problem and went in to loosen it up. Everything in that spam trap auto-expires in 7 days, and I missed it. Discovered only after payments to first-round non-respondents had be re-distributed to others, and the whole deal closed.
