Keep informed about the recent Fedora 40 security notice regarding OpenSMTPD, highlighting vital enhancements and security resolutions.
opensmtpd: 7.4.0p1 release

Summary

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.
