You are correct, it does not make sense for an ISP to block it's users
from accessing any SMTP server.
But, I'm just using my company as an example... Any network
operator/ISP _can_ block connections to other SMTP servers if they wish.
The only logical reason to do so is to prevent rogue SMTP/Spam servers
from setting up shop on their network. Which is precisely what is done here.
