Dovecot’s global market share grows to 75%

By Timo Sirainen, Co-Founder Dovecot

The results of this year’s Open Email Survey are in and Dovecot’s IMAP Server market share continues to grow rapidly year-over-year. After scanning 2.1 billion IP addresses Dovecot was found to have a market share of 75.1%, up from 71.2% last year. This translates to an extrapolated total of over 4 million live Dovecot servers world-wide.

The Open Email Survey, which this year covered over 50% of all observable IPv4s worldwide, has been tracking IMAP server software since 2012. During those five years, Dovecot has increased its market share from just under half (48.37%) to three quarters of the IMAP server market.

In 2015, Dovecot became part of the Open-Xchange family with a shared and deep-rooted commitment to an open source model for delivering trusted applications. Together our aim was to become the world’s leading provider of open source cloud software for ISPs, telcos, cable companies and cloud providers.

This news is a testament to the success of Dovecot’s commercial ISP and telco offering, Dovecot Pro. The benefits of secure, stateless, reliable and scalable email services are clearly apparent to service providers. Dovecot Pro is designed for critical deployments where hardware utilisation, uptime and performance are crucially important. Professional Dovecot support means that you are never alone if something goes wrong, something our customers value enormously.
