Insight

Insight

OpenSMTPD is a FREE implementation of the server-side SMTP protocol as defined by RFC 5321, with some additional standard extensions. It allows ordinary machines to exchange e-mails with other systems speaking the SMTP protocol. Started out of dissatisfaction with other implementations, OpenSMTPD nowadays is a fairly complete SMTP implementation. OpenSMTPD is primarily developed by Gilles Chehade, Eric Faurot and Charles Longeau, with contributions from various OpenBSD hackers. OpenSMTPD is part of the OpenBSD Project. The software is freely usable and re-usable by everyone under an ISC license. This package uses standard 'alternatives' mechanism, you may call '/usr/sbin/alternatives --set mta /usr/sbin/sendmail.opensmtpd' if you want to switch to OpenSMTPD MTA immediately after install, and '/usr/sbin/alternatives --set mta /usr/sbin/sendmail.sendmail' to revert back to Sendmail as a default mail daemon.
