Aid4Mail’s filtering capabilities are extremely powerful and flexible. Being able to filter for emails between users that rejects emails that contain recipients with certain email domains is possible with a regular expression.

For example, you want to filter for any emails that were sent to email addresses with an email domain other than @aid4mail.com. This means that you only want to collect emails that contain recipients (To, Cc, Bcc) outside the @aid4mail.com email domain.

Here are some examples of emails Aid4Mail will reject and emails that will be collected:

Reject– To:  Ben@aid4mail.com  CC: Tim@aid4mail.com
Collect– To: Sally@gmail.com
Collect– To: Betty@aid4mail.com; Jim@yahoo.com CC: Nancy@aid4mail.com
Collect– To: Alex@aid4mail.com; Betty@aid4mail.com CC: user@fookessoftware.com
Reject– To: Mike@aid4mail.com

In order to accomplish the above, you would use a regular expression like this:

Recipients:{[R]=\w+@(?!aid4mail\.com)}

In Aid4Mail, you would simply add this to the item search query as shown here:
As you can see from above, Aid4Mail provides you with the ability to create complex search queries to make sure you find and process the emails that are needed for your investigation.
