Hello, The skarnet.org mailing-lists use a probing system to automatically unsubscribe addresses that don't work anymore. When an address fails 3 consecutive times, it gets removed.
In the past year, or sometimes at an older time than that, a lot of addresses have apparently failed enough probes and been unsubscribed, even still working addresses. Only today was it brought to my attention. I have manually resubscribed all addresses that got removed because of a probe. If they keep failing, either they don't work and their being removed again won't be a problem, or there's something more serious going on and I'll have to investigate what's happening. If you don't want to be on the mailing-lists anymore, please unsubscribe manually. Sorry for the inconvenience.
