sendmail.exe: Error during delivery. Service not available, closing transmission channel
- by user2810332
I have a module in my system that will trigger an email and send it to user. The email will be sent to user when the product in my system is going to expired soon. I test the whole module in localhost and there is no problem with it. Then, I finally moved the module in my server but it gives this error.
sendmail: Error during delivery: Service not available, closing transmission channel.
It will also create a notepad in my desktop that contains information like this :

May I know what is the problem of this error ? Is it something like firewall in the server that block my sendmail.exe or anything else ? FYI, I'm using Wamp and Sendmail to send the email. This is my first time seeing error like this. I need an explanation on this. Thank you.
