smtp mail logic clarification
Posted: Thu Dec 21, 2006 9:43 am
let us say there are two servers
1. server one runs a smtp program to send mails
2. server two runs a web application and the web application sends emails using server one's smtp
let us assume there is a situation like this.
server one goes down and it means smtp program is not running
server two is running and the web application is also running
web app in server 2 keeps sending mails eventhough server one is down
my questions
1. what will happen to all the mails that are sent by web app in server 2 to server 1 when server 1 is down?
2. if they will be delivered, can you explain how this process actually happens?
thanks for any kind of information you are going to provide me in this context.
