Release Notes: This release preserves upper/lower case information while mapping addresses with canonical, virtual, relocated, or generic maps. Some obscure behavior was removed from the smtp_tls_per_site without a change in the user interface.
Release Notes: This release provides a plugin architecture for SASL authentication.
Release Notes: This release adds configurable text for (non)delivery status notifications and support for multiple ISP accounts, implemented with sender-dependent relayhosts and with sender-dependent SASL passwords.
Release Notes: This snapshot is expected to be the last one before STARTTLS support is merged into the main source tree. The NIS+ client by Geoff Gibbs is now part of the Postfix source tree. By default, Postfix no longer appends its own domain to addresses in message headers from remote clients. Thus, spam from poorly written software no longer looks like it came from a local user. Postfix either does not rewrite remote message headers at all, or it rewrites headers and appends the domain name that is specified with the remote_header_rewrite_domain parameter.
Release Notes: This release adds per SMTP client message rate and recipient rate limits. These limit the number of MAIL FROM or RCPT TO requests per time unit, regardless of whether or not Postfix would have accepted them otherwise. Additionally, SASL authentication attributes are now stored queue files and are passed on to delivery agents. The first delivery agent to take advantage of this is the pipe(8) delivery agent.
Release Notes: This snapshot catches up on Duchovni features and adds some polish to session caching.
Release Notes: This release features consistent XCLIENT/XFORWARD protocols and fully working fallback to an alternate SMTP server if a delivery attempt fails in the middle of a session.
Release Notes: This snapshot added a few features and some safety checks in preparation for the transition from post-2.0 snapshot releases to the official 2.1 release.
Release Notes: This release adds support to blacklist domains by their mail servers or by their name servers. It can also be used to block mail from domains that resolve to Verisign's mail dump for non-existent domains. It supports LDAP session sharing between lookup tables in the same Postfix process.
Release Notes: This release adds policy delegation to an external server as well as support for multi-valued RBL services.
