Title: OpenSMTPD 7.3.0p1 Released with New Features and Enhancements
OpenSMTPD 7.3.0p1 has been released two and a half years after the last update. The server, developed under the OpenBSD project, aims to provide a simple alternative to Sendmail. It supports most of the RFC 5321 specification requirements and implements protocol extensions such as user authentication (SMTP Auth), TLS-shifting traffic, notification of DSN delivery (Delivery Status Notification), extended status codes (Enhanced Status Codes), and spam-blocking by integrating with Spamd, among others. It works in FreeBSD, NetBSD, Dragonflybsd, MacOS, and Linux.
Previously, a postponement issue of OpenSMTPD based on the code base from OpenBSD 6.8 was published in December 2020. The new issue is now synchronized with OpenSMTPD from the OpenBSD 7.3 composition and includes various noticeable changes and additions.
The release includes added option “-a”, allowing authentication before sending a message. In the listeners for TLS, the possibility of setting up several certificates selected depending on the name of the domain (SNI) has been added. The release also includes a transition from the use of the Libtls library and the implementation of support for TLS “Cafile = (Path), Nosni”, “Noverife”, and “Servername = (Name)”.
Users can now select the parameters of ciphers and TLS protocols in SMTP, and the default TLS check for outgoing connections “smtps: //” and “smtp+tls: //” has been integrated. Also, a search has been added to select the certificate used by the names present in the certificate itself, not by the name of PKI. The release eliminates memory leaks and errors that lead to emergency completion.
OpenSMTPD 7.3.0p1 can be downloaded from the official OpenSMTPD website. Users are advised to upgrade to the latest version to take advantage of new features and enhancements.
