-Now you need to sort out the private key. Copy the private key and paste it into a text editor, like notepad. This document needs to be saved into the VPOP3 directory, as a file called **domainkey_<domain name>_<selector>.key** (e.g. **domainkey_example.com_1532654.example.key**). +Now you need to sort out the private key.
