- update to 3.1.1:
- The new address_verify_pending_request_limit
parameter introduces a safety limit for the number of address
verification probes in the active queue. The default limit is 1/4
of the active queue maximum size. The queue manager enforces the
limit by tempfailing probe messages that exceed the limit. This
design avoids dependencies on global counters that get out of sync
after a process or system crash.
- Machine-readable, JSON-formatted queue listing with "postqueue -j"
(no "mailq" equivalent).
- The milter_macro_defaults feature provides an optional list of macro
name=value pairs. These specify default values for Milter macros when
no value is available from the SMTP session context.
- Support to enforce a destination-independent delay between email
deliveries. The following example inserts 20 seconds of delay
between all deliveries with the SMTP transport, limiting the delivery
rate to at most three messages per minute.
smtp_transport_rate_delay = 20s
- Historically, the default setting "postscreen_dnsbl_ttl = 1h" assumes
that a "not found" result from a DNSBL server will be valid for one
hour. This may have been adequate five years ago when postscreen
was first implemented, but nowadays, that one hour can result in
missed opportunities to block new spambots.
To address this, postscreen now respects the TTL of DNSBL "not
found" replies, as well as the TTL of DNSWL replies (both "found"
and "not found"). The TTL for a "not found" reply is determined
according to RFC 2308 (the TTL of an SOA record in the reply).
Support for DNSBL or DNSWL reply TTL values is controlled by two
