What happens when the email you send out returns


I have an application whic send out email with attachmnet,it works wonderful. I was wondering what happens for some reson that email returns for example wrong emialId. Is there any log where i can go and check it out



When the mail is undelivered due to wrong email id, it is returned to the mail id specified in the from parameter. The error is logged into server.log file with the message:Error processing email message. [B2BSERV.0068.9003] Invalid service: Undeliverable:
