Orange blocking ports


[link to this post]
 
Does anyone know why Orange appear to be blocking ports from 3rd party email servers

Such as Namesco Authenticated smtp appears to be blocked on 25,2525 and 587

usually it is to counter the sending of spam eg by botnets

It is definitely a weird on as Orange only appered to have started the port blocking on thursday and it effects anyone with an authenticated smtp service with 3rd party companies such as Namesco.

587 is an auth only port so thats stupid to block that.

any port can be used for anything, perhaps they have an issue with traffic on that port

Orange doesn't block Authenticated Port 587 to Hotmail, so it wouldn't to Namesco.

It blocks all Port 25s except its own to combat spam.

Except that multiple Namesco authenticated smtp customers are reporting that no authenticated traffic is being allowed through their Orange connection.

Also the Namesco Auth logs are reporting authentication failure indicating the the network is stripping the authenticated headers.

Hmmm, several people who I help with their PCs are having problems.

Due to the continual problems with the Orange SMTP server I set them up with their own domains & hosting, thereby giving them their own mail server and addresses.

Result several happy users.

Now it seems Orange have decided to not only block SMTP traffic on port 25 but also 587 (which a lot of 3rd party mail servers use) and FORCE their customers to use their flaky, unreliable SMTP server.

I can't change the mail servers' port so not sure how I am going to get those users happy again.

Sounds like a detrimental change to T & Cs to me if it isn't very short-term.
