Today with nothing better to do, I spent few time to look into my Linux servers and just to verify all the services running as normal. When it come to my Sendmail server I found out that my email can’t be sent out with below error message :-

Feb 18 21:21:06 (none) sm-mta[1598]: n1GGL5Pd029739: to=, delay=1+21:00:01, xdelay=00:00:00, mailer=relay, pri=9752261, relay=smtp-proxy.tm.net.my., dsn=4.0.0, stat=Deferred
Feb 18 21:21:06 (none) sm-mta[1598]: n1GCHRXA032586: to=, delay=2+01:03:38, xdelay=00:00:00, mailer=relay, pri=10741056, relay=smtp-proxy.tm.net.my., dsn=4.0.0, stat=Deferred

I still remember no modification on my sendmail for the past 3 months but why suddenly this thing happened? After few try sending email via thunderbird, kmail & etc but still no success. As we know, our mail server must use TMnet smarthost & all email must send via port 587. Finally I telnet tmnet server one by one and you know what, out of sudden, currently TMnet only allow your email send via old port which is port 25. No notice or announcement made by TMnet and they surely good on that. Bravo TMNET keep us headache….
