New Features in Exim
--------------------
ratelimit = <m> / <p> / <options> / <key>
- If the average client sending rate is greater than m messages per time
- period p then the condition is true, otherwise it is false.
+ If the average client sending rate is less than m messages per time
+ period p then the condition is false, otherwise it is true.
The parameter p is the smoothing time constant, in the form of an Exim
time interval e.g. 8h for eight hours. A larger time constant means it
cdb {DB/ratelimits.cdb} \
{$value} {RATELIMIT} }
+TK/01 Added an 'spf' lookup type that will return an SPF result for a given
+ email address (the key) and an IP address (the database):
+
+ ${lookup {tom@duncanthrax.net} spf{217.115.139.137}}
+
+ The lookup will return the same result strings as they can appear in
+ $spf_result (pass,fail,softfail,neutral,none,err_perm,err_temp). The
+ lookup is armored in EXPERIMENTAL_SPF. Currently, only IPv4 addresses
+ are supported.
+
+ Patch submitted by Chris Webb <chris@arachsys.com>.
+
+PH/02 There's a new verify callout option, "fullpostmaster", which first acts
+ as "postmaster" and checks the recipient <postmaster@domain>. If that
+ fails, it tries just <postmaster>, without a domain, in accordance with
+ the specification in RFC 2821.

Version 4.51
