This program works a lot like SenderDomainExtractor but supports multiple email fields. Will extract a list of unique domains and unique email addresses.
|
| 10 |
|
| 11 |
Will skip any that are internal and do not have a @ symbol, just FYI.
|
| 12 |
|
| 13 |
Doesnt support unicode, so convert to ascii first.
|

WARNING: removes the headder from the dat, so make sure you have one.
