SMTP code: 503
Hi,
I got this situation and I have no idea why it caused SMTP code 503...please help me.
This is what I tried to do. I try to run my program and send warning email if a condition is satisfied. But I cannot receive any warning emails so I use a lan analyzer to detect what's wrong...and I got this SMTP code 503. What will cause this problem and how can I solve this problem. My program runs fine with other Linux 9.0....not sure which setting in Linux I should modify...Any idea????

OK...my mail server is on our network...
I write this program...and it's an executable program in C++...
So what should I do?

Sorry for taking this long...but I'm still waiting for the reply after I adding HELO in my program..However, I think this will work! Thank you~~~
You're not authenticating with your mail server, that's what that business is about. I don't know what program you are using, but your mail server is set to require authentication for all non-local smtp transfer it looks like. You may want to configure that program to authenticate when it sends mail or make your SMTP server not require authentication if requests are coming from your lan.
Cheers!
