Councilman Update:
Great news -- the en banc First Circuit has issued its opinion in United States v. Councilman, a very important Internet privacy case, and reversed the district court. I'm working my way through the opinion now and will offer some thoughts later in the day. Thanks to Howard for the link.
I will also be downloading and seeing how much of my rationales the Court (unknowingly) adopted...
Councilman was using 1980s software, sendmail and procmail.
Congress either had to have screwed the statute up from the beginning in 1986 or have intended to cover exactly this conduct.
The court got there eventually, but not even a footnote for the timeline?
1979 - delivermail, sendmail forerunner.
1983 - sendmail released.
1986 - Electronic Communications Privacy Act.
1991 - procmail released.
1998 - Councilman orders interception of emails.
