# MAIL FROM WHO
Tool to retrieve all e-mail addresses from a configured user. The e-mail addresses will be written in a CSV-file,
ordered by the domains of the senders. 
## Configuration
In the project you'll find the file **appsetttings.json**, in which you have to configure
- Username - Used to log in to the mail account. Sometimes this is only the name (john), or the complete e-mail
address (john@mail.com)
- ImapServer - FQDN of the IMAP server
- SslPort - SSL port to use on the IMAP server. Usualy 993
- IntermediateFile - In this file the tool will store all e-mail addresses (unsorted and likely with duplicates)
- CsvFile - End result in CSV-format. The first column contains the e-mail addresses, the following the name(s) use with
the address (can also be none), e.g.
	- john@mail.com,John,John Doe

The tool will prompt for the password. For security reasons, the password can't be stored in the configuration.
