Yes. You can use Starkit to collect mail from other email services like Gmail or Hotmail or from any other POP3 or IMAP email account.
Apart from viewing and replying to email accounts at your domain created using Starkit, if you use several email accounts with different providers, we offer you a way to manage them all in one place: Starkit’s Mail Collector. It allows you to retrieve and send email from all your accounts from Gmail, Outlook.com or Yahoo or any other POP3 or IMAP email account. This allows you to have the privacy and security benefits of the Starkit email system, but still hold onto your well established and known email address.
If you already have your own domain you can add it and use it with Starkit. By adding a domain on Starkit:
a) You can easily create email accounts for you and other people in your organization at your domain (i.e. email@example.com), through a simple administration screen, without requiring the help of an IT professional.
b) You will no longer need to maintain your in-house mail server or pay fees to your current email service provider (i.e. Google Apps or Hosted MS Exchange services).
