OpenSMTPD 7.7.0p0 released

13 May, 2025 by op@openbsd.org | openbsd
OpenSMTPD is a FREE implementation of the SMTP protocol with some common
extensions. It allows ordinary machines to exchange e-mails with systems
speaking the SMTP protocol. It implements a fairly large part of RFC5321
and can already cover a large range of use-cases.

It runs on OpenBSD, NetBSD, FreeBSD, DragonFlyBSD, Linux and OSX.

The archives are now available from the main site at www.OpenSMTPD.org

We would like to thank the OpenSMTPD community for their help in testing
the snapshots, reporting bugs, contributing code and packaging for other
systems.

This is a major release with bug fixes and documentation improvements.


Dependencies note:
==================

This release builds with LibreSSL, or OpenSSL >= 1.1.

It's preferable to depend on LibreSSL as OpenSMTPD is written and tested
with that dependency. OpenSSL library is considered as a best effort
target TLS library and provided as a commodity, LibreSSL has become our
target TLS library.


Changes in this release:
========================

 - mail.lmtp: Correctly propagate LMTP permanent failures to smtpd.
 - Fixed connect filter request documentation in smtpd-filters.7.
 - Updated to new imsg APIs.


Checksums:
==========

Verify:
=======

Starting with version 5.7.1, releases are signed with signify(1).

You can obtain the public key from our website, check with our community
that it has not been altered on its way to your machine.

    $ wget https://www.opensmtpd.org/archives/opensmtpd-20181026.pub

Once you are confident the key is correct, you can verify the release as
described below:

1. download both release tarball and matching signature file to same directory:

    $ wget https://www.opensmtpd.org/archives/opensmtpd-7.7.0p0.sum.sig
    $ wget https://www.opensmtpd.org/archives/opensmtpd-7.7.0p0.tar.gz


2. use `signify` to verify that signature file is properly signed and that the
   checksum matches the release tarball you downloaded:

    $ signify -C -e -p opensmtpd-20181026.pub -x opensmtpd-7.7.0p0.sum.sig
    Signature Verified
    opensmtpd-7.7.0p0.tar.gz: OK


If you don't get an OK message, then something is not right and you should not
install without first understanding why it failed.
