MITIGATING SPAM IN TM NETWORK

Our valued customers,

Telekom Malaysia Berhad (TM) wishes to inform you about its initiative in combating spam in its Internet Protocol (IP) network to improve our quality of service.
Recently, many anti-spams, organizations have blacklisted a large number of IP addresses from TM’s network. Due to this, many customers have been unable to send emails from their mail server to companies, which are using databases from the above mentioned anti-spam organizations.
These spamming activities by a small group have affected a large number of our customers, regardless of the nature of their usage.

Therefore, TM is taking immediate action to address this issue where TM will block OUTBOUND Simple Mail Transfer Protocol (SMTP) traffic or port 25 for all outgoing e-mails from dynamic IP addresses. Only Outbound SMTP traffic from smtp.streamyx.com and smtp.tm.net.my will be permitted. This will be done in phases, starting in the Brickfields area, subsequently followed by Klang Valley area before being implemented nationwide.

With this exercise, Streamyx customers with dynamic IP addresses, who have their own mail server will not be able to send out-going e-mails. As an alternative, TM will be providing customers with two options. Customers may choose to relay their mail server to our SMTP or use port 587 for any outgoing e-mails. Kindly refer to the following links for configuration details:

How to configure the relay for client -http://webmail.tm.net.my/info/proxy.html
How to configure port 587 for client -http://webmail.tm.net.my/info/port587.html
How to setup relay host in mail server- http://webmail.tm.net.my/info/smtp-proxy.html
How to configure port 587 for mail server – Customers may need to refer to their administrator or hosting service provider to support and turn on port 587 for their mail server.

Kindly be assured that TM is proactively taking all possible measures to ensure that these spamming activities do not reoccur in the future. We seek your kind co-operation to implement the necessary security measures to protect your computers, which are connected to the Internet from any e-mail abuse, virus infection, spyware or malicious code.
