Re: Port 25 - Blacklash
- From: Adam Jacob Muller

The fact that most people did not complain is not likely due to the
fact that they were not annoyed by the change, but rather it's easier
to simply get around it than it is to bother complaining to network
admins.
For example, about 2 months ago, comcast decided to block outgoing
port 25 from my entire neighborhood. I called comcast, and while
sitting on hold I had the idea to setup a ssh tunnel to a machine at
work and viola problem solved before anyone from comcast even
answered the phone.

Paul,
For any educational institutions on this list - what has been the
impact on
your mail services once your ISP started blocking port 25 - what
if any was
the backlash - and how difficult was it to provide alternatives ...
587,465
etc ...
Our ISPs don't filter our traffic. If they consistently did, they
probably
wouldn't be our ISPs for long.
OTOH, the question that you didn't ask was if educational institutions
themselves are blocking port 25 from their users :)
In our case, yes we are. We only allow SMTP connections from our dorm
subnets to the campus mail servers. Personally, I thought there
was going to be a huge backlash from our community when we put this
in about
a year ago. Of the 12,000 students that this affected, I believe
two have
inquired about it but didn't really have an issue with it.
Eric :)
