I need a quick and simple software/script which logs into my webmail and extracts all email addresses (apart from the sender's email address of course!) from the body of all messages found in the inbox.
The output file must be in a .CSV format.
And there should be no duplicates. E.g. if an email address is mentioned 2 or 3 times in the body of the email, then this should be cut down to 1, for the CSV file.
