first of all: Zammad rocks!
There should be a way to import Messages from an 3rd party Mail app like Outlook.
Some customers send their support-mails to firstname.lastname@example.org instead of email@example.com.
So the mails are received by an company Exchange-Server or other Mail-System.
There should be an easy way, to move these mails to zammad, with correct sender (customer) and correct title.
Any ideas of this?
