   Why is Port 25 for Email Submission Not Supported?

   Comcast's rationale for blocking outbound SMTP traffic from their residential-class customers.

   • comcast
   • port25
   • smtp
   • spam

     Somehow I'd thought the world had moved beyond wholesale port-blocking for spam-control. Guess not.

     The whole "[any computer on a residential-class line] should never send email at all" reasoning is incredibly vexatious: EVERYONE should be sending their #email directly from trusted node to trusted node without having to let their ISP cache and read their messages.

     Apparently I can still do #P2P #SMTP on #Comcast "business" lines; the price of #privacy / #autonomy is $60/month extra + 2-year commitment.

     @rozzin But if we're not in corporate silos how is the NSA et al supposed to intercept our messages easily?

     @maiyannah @rozzin I kinda regret that I used my main email as Yahoo all those years ago as Yahoo is the worst at giving information to the NSA. But alas, I tied literally all my important stuff in my life to that one email...

     @rozzin I believe #Verizon (now #Frontier in #California) #FiOS submits its IP ranges to spam blockers, so even if one could evade VZ's own port-blocking, reputation would prevent message from reaching most recipients.

     @rozzin I believe #Verizon (now #Frontier in #California) #DSL and #FiOS submits its residential IP ranges to spam blockers, so even if one could evade VZ's own port-blocking, reputation would prevent message from reaching most recipients.

     @maiyannah, I encourage those who do fear law-enforcement being hampered by routine privacy to just explicilty CC NSA on all their e-mail.

     Hm. I should have used "M-x spook" on that message before sending: http://www.fnal.gov/docs/products/emacs/emacs/emacs_29.html#SEC308
