###Email Hell
We just found out that there is a bug in production that our e-mail function was iterating errantly and sending duplicate e-mails to many users. We need to fix this quickly but we don't want to send out a mass apology letter to all of our users.
Our sysadmin gave us the SMTP logs and we need to process the logs and identify which users received multiple e-mails so that we can directly send them a follow up e-mail explaining the situation and offer super cool swag to keep them on as customers.
Also, the boss wants this done ASAP, we don't have time to do this manually...HAAALLLLPPP!
###The Fix
Implement a module pattern that takes in the data below from our logs that has a list of all the email addresses that emails were sent to, and create a report of all of the unique e-mails and the number of times an e-mail was sent to each address.
###The Gotcha
We're not sure when we'll get out a hotfix for the errant code so this may happen again. Can you write this in a way that we can do this on our own so we don't have to bother you every time this happens?
Thaaaaanks :D
