OpenSMTPD 7.5.0p0

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 multiple bug fixes and new features.

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:

Added support for RFC 7505 "Null MX" handling and treat an MX of "localhost" as it were a "Null MX".
Allow inline tables and filter listings in smtpd.conf(5) to span over multiple lines.
Enabled DSN for the implicit socket too.
Added the no-dsn option for listen on socket too.
Reject headers that start with a space or a tab.
Fixed parsing of the ORCPT parameter.
Fixed table lookups of IPv6 addresses.
Fixed handling of escape characters in To, From and Cc headers.
Run LMTP deliveries as the recipient user again.
Disallow custom commands and file reading in root's .forward file.
Do not process other users .forward files when an alternate delivery user is provided in a dispatcher.
Unify the table(5) parser used in smtpd(8) and makemap(8).
Allow to use table(5) mappings on various match constraints.

Portability fixes:

re-add ASR_IPV4_BEFORE_IPV6 compile-time knob to prefer connecting to IPv6 instead of IPv4.
update asr(3) and imsg with OpenBSD.
fixed rpath handling on NetBSD in the configure.

Checksums:

SHA256 (opensmtpd-7.5.0p0.tar.gz) = 84f5c1393c0c1becc72ceea971e0abd7075b2ca7e4e1f8909b83edfd8de0c39c

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:

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

$ wget https://www.opensmtpd.org/archives/opensmtpd-7.5.0p0.sum.sig
$ wget https://www.opensmtpd.org/archives/opensmtpd-7.5.0p0.tar.gz

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-7.5.0p0.sum.sig
Signature Verified
opensmtpd-7.5.0p0.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.
