The error message is like following:
503 must have sender and secipient first.
I check all the setting for my Outlook Express, but it seems like there's no 
option for me to set it in TNMSMTP component. 
Btw, how to do it using Indy component though ??

Hi Soonhuat,

Hmm, if that is the case we need to confirm a few things...

What error message does it give?
Check and confirm that the outlook express settings are the same as the
settings being used in your email application ie.

pop3 server
smtp server
authentication methods for the pop3 (normally username and password)
authentication methods for the smtp (normally username and password)
from email address, and all the nitty grittys secure password authentication
etc...

ps: i could help you more if you were using indy components free with source
