In Q1 of 2018, AppRiver will be upgrading our CipherPost Pro® service with several great, new features. With this upgrade, you can look forward to enhanced, faster webmail and "sign on the line" for e-signature. This new e-signature feature is easy to use and complies with e-signature legislation. In preparation for this upgrade, periodic maintenance will be performed on the CPP service over the next month. Please note that this may result in periodic service unavailability during off-peak time for some users. We apologize for any inconvenience this may cause as we work to bring you a better CPP experience.
