A recent local news item describes a woman who received notification of a lawsuit in her "junk email" account while she was in the hospital, giving 21 days to reply. She did not reply, and a judgement was rendered.
The linked article mentions that Illinois law on notification of lawsuits recently changed allowing for it to be done via email, but it does not go into detail about what the new law says regarding responsibilities the sender has to verify the email address is correct, working or if the target is aware-of and has read the email.
So I'd like to ask about those details here.
