GMail vs Kerio Connect
Last updated: February 16, 2018
Gmail is a free, advertising-supported email service provided by Google. Users may access Gmail as secure webmail, as well via POP3 or IMAP protocols. Gmail's spam filtering features a community-driven system: when any user marks an email as spam, this provides information to help the system identify similar future messages for all Gmail users. Google also provides GMail alternative for business - G Suite Mail.
Kerio Connect is a commercial mail and groupware server developed by Kerio Technologies. It runs on Windows, Linux, and Mac OS X. Its features include encrypted access using SSL, anti-virus and anti-spam protection, native over-the-air handheld synchronization, webmail interface, connector for Microsoft Outlook and groupware features.
2014 - Google+ users now can send messages to your GMail inbox to take on Kerio Connect
Google continues searching opportunities to promote its social network Google+. At this time - at the expense of GMail. If you use GMail - know that now anyone on Google+ (even without knowing your email address) is be able to send email-messages to your GMail-inbox. But if you do not want to receive these new commercial/spam offers - you can disable this feature (in GMail Settings) or allow only your "Google+ circles friend" to email you. On the other hand, if you're on the other side of marketing - you now have the great opportunity to contact those people that you previously couldn't contact. You just need to find these people on Google+ before they disable this feature in their GMail settings.
