Dear Valued Customer,

Telekom Malaysia Berhad wishes to inform its customers about TM’s initiative in combating spam in its Internet Protocol (IP) network to improve our quality of service.

Recently, many anti-spam 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 who might be using database from the abovementioned anti-spam organizations.

These spamming activities by a small group have affected a large number of our customers, regardless of the nature of their Internet usage.

Therefore, TM is taking immediate action to address this issue. Effective 3 December 2007, TM will block OUTBOUND Simple Mail Transfer Protocol (SMTP) traffic or port 25 for all out going e-mails from dynamic IP addresses. Only Outbound SMTP traffic from smtp.streamyx.com and smtp.tm.net.my will be allowed.

With this implementation, Streamyx customers who have their own mail server will not be able to send e-mails. As an alternative, TM is providing an open relay server for these customers who use dynamic IP addresses. Kindly refer to http://webmail.tm.net.my/info/proxy.html on how to configure your email client in order to utilize the relay server. Alternatively, your e-mail administrators can refer to http://webmail.tm.net.my/info/smtp-proxy.html as a guide to configure your company’s email servers.

Please 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 that are connected to the Internet from any e-mail abuse, virus infection, spyware and malicious code.

For further enquiries and assistance, email us at [email protected] or call TM at 100 and select ‘Internet Services’. more

TMNet announced that outbound SMTP connections on port 25 will be blocked for Streamyx dynamic IP connections, citing spam control as the reason. No prior notice was given other than an announcement on their website (who will visit them anyway) on the day that it’s scheduled to be implemented. If you are having problem with your email, you should know who’s the culprit and who’s the one to be blamed.

I know bout this because, my college friend sent me an email yesterday mentioning about this and I have to thank him for the information.

TM Net said a large number of IP addresses from its network have been blacklisted by many anti-spam organizations recently, causing its customers to be unable to send emails from their mail server to companies who might be using databases from these anti-spam organizations.

To mitigate the problem, effective yesterday (December 3, 2007), TM decided to block OUTBOUND Simple Mail Transfer Protocol (SMTP) traffic — or port 25 — for all out going e-mails from dynamic IP addresses. From now on, all outbound SMTP traffic (outgoing emails) must pass through smtp.streamyx.com and smtp.tm.net.my. No second choice.
