The story
History
The company was founded in 1999 by Eric Allman in Emeryville, CA. Eric also created sendmail, an open source mail transfer agent while he was a student and a staff member at the University of California, Berkeley. It is the commercial version of the open source version of sendmail.
Managing Email
In 2005, Sendmail released the Sentrion email infrastructure platform to address the need for full-content message inspection, enabling policy-based delivery of all human and machine-generated email.
Hybrid Cloud
In 2012, Sendmail partnered with Mimecast to provide hybrid-cloud email security, archiving and continuity as some predicted that 2013 would see more organizations implementing hybrid cloud computing strategies to reduce cost and complexity of their messaging infrastructure.
Machine-Generated Email
In 2012, Sendmail released Sentrion REAC (Rogue Email Application Control) amid growing security, compliance and other concerns posed by the growth of application-generated email and migration of email to the cloud.
Acquired by Proofpoint
In 2013, Sendmail was acquired by security-as-a-service company Proofpoint, Inc.
