I used sendmail on a unix box to send out a large number of emails from a customer database.
The problem is that recipients whose emails returned to my /var/spool/mqueue folder, received duplicate emails.
There were no duplicate email addresses in my email list, and I am at a stump as to how this happened.
I understand that the recipient's mail server may have been too busy or down, but why didn't my mailer daemon detect when the emails went through successfully?
