Education and training

Born in El Cerrito, California, Allman knew from an early age that he wanted to deal with computing later in life, breaking into his high school's mainframe and later using the UC Berkeley computing center for his computing needs. In 1973, he entered UC Berkeley, just as the Unix operating system began to become popular in academic circles.

Sendmail and other contributions

As the Unix source code was available at Berkeley, the local hackers quickly made many extensions to the AT&T code. One such extension was delivermail, which in 1981 turned into sendmail. As an MTA, it was designed to deliver e-mail over the still relatively small (as compared to today's Internet) ARPANET, which consisted of many smaller networks with vastly differing formats for e-mail headers.

Sendmail soon became an important part of BSD, the Berkeley Software Distribution and continues to be the most widely used MTA on Unix and Linux systems today, despite its somewhat complex configuration syntax and frequent abuse by Internet telemarketing firms. In 1998, Allman founded Sendmail, Inc., headquartered in Emeryville, California, to do proprietary work on improving sendmail.

Allman is credited with popularizing the Allman style indent style, also known as BSD indent style.

Private life

Openly gay, Allman lives in Berkeley, California with his partner of over 20 years, Marshall Kirk McKusick, a lead developer of BSD.

"There is some sort of perverse pleasure in knowing that it's basically impossible to send a piece of hate mail through the Internet without its being touched by a gay program. That's kind of funny." —Eric Allman
