- Gordonjcp 4y agoThat's basically what domestic ISPs do. You will probably find that outbound traffic on port 25 is blocked, because all of your pwn3d inadequately-patched Windows machines are spam cannons now.
- bombcar 4y agoYep - some block it so hard you have to use other ports to communicate with offsite mail servers (and why various other ports are found, now). Some ISPs will remove the block if you ask.
- chrismeller 4y agoI’ve come to treat residential ISPs as basically a transit for HTTP. As someone else in the thread pointed out that’s all that 99.99% of customers care about, and unfortunately you’re talking about a lowest common denominator here.
