Many email hosting subscribers in Malaysia are having problems sending out emails from their email clients including Microsoft Outlook, Outlook Express or Eudora. Well, this is happened after a harsh decision from Telekom Malaysia to block OUTBOUND Simple Mail Transfer Protocol (SMTP) traffic or port 25 for all out going emails from dynamic IP addresses. Only Outbound SMTP traffic from smtp.streamyx.com and smtp.tm.net.my will be allowed.
This affects only users of Streamyx Broadband and other TM Internet Subscribers. This action was taken to fight SPAM in TM’s network to improve quality of connection.
TM has suggested a new SMTP server (smtp-proxy.tm.net.my) to be used as an alternative to the original SMTP you have configured in your Outlook or Outlook Express. Another set of problem arises from this alternative:
1. What will happen if all the traffic (nationwide) routes to this single ‘open-delay’ smtp server? What is the dedundancy support? Will your emails be in queues???
2. You can’t send out emails if you are out of Streamyx or TM networks when you are using smtp-proxy.tm.net.my
Although this is a common practice by ISPs in the old days, it seems to be less practical especially when most people are moving around using different connections, etc.
