Re: Can ISP block selected e-mails?
the question is very specific, but also very vague...
look at it this way...
when an ISP blocks a website, usually they are blocking the connection to a specific IP address,
so an ISP can feasibly drop all traffic from a specific range. this could be Yahoo servers, this would be a complete deny... so you wouldn't get any emails and never know that an email had been sent...
now, can an ISP take a message desitned for your IP address, feasibly and ISP could block port 25 to stop you getting sent emails, but this would be a complete block, not a block from a certain person.
if your ISP relays your message (at the actual message level using SMTP) then they could filter the message in the same way a spam filter would/could so they could do whatever they liked from it.
can an ISP stop you looking at your Yahoo messages on their webmail?
filter out the message part leaving only the message headers?
