TM, in their official press release described the act to block all 3rd party as one of the step to fight Spam. Following this, most of the companies in Malaysia who is using Streamyx broadband are affected after switching to smtp-proxy.tm.net.my. Problem including email delay and lost.
One of the latest updates I have received is, email delivered / delayed through smtp-proxy.tm.net.my is also marked as Spam by many major free email service provider including Yahoo Mail!
=) Thanks for pointing out the problem…i believe many people will face this problem also but never notice their email went into junk.
