Telekom Malaysia Berhad (TM) has decided to 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.
Solution to this blockage, IonBytes server accepts SMTP connections on both port 25 and port 587. If you are affected by the blockage, kindly reconfigure your email client's SMTP settings to use port 587 instead of 25.
