When sending emails, I have set my Linux Box to represent as "aaaaaa.com", which is a non existing domain. Now if I send an email from this linux box [aaaaaa.com domian] to some yahoo.com address which does not exist, say bbbbb@yahoo.com, then the Yahoo SMTP will bounce this mail back. The Yahoo SMTP will bouce the mail back to the SMTP of aaaaaa.com [ which does not exist ]. So what will happen to the bounce back mail. WHat will yahoo's SMTP do.throw it in >>NULL, or what.
If I understand the SMTP / TCPIP correctly then this mail will be bounced back to my linux box then & there. But what if my linux box gives it to the yahoo SMPT which has along que, and I disconnect my Linux box from the internet.
I hope I have been able to exlpain my query. Just getting some fundas cleared.
