Here comes exiscan-acl revision 20 for Exim 4.33.
http://duncanthrax.net/exiscan-acl/
One new feature: Multiple spamd server support, both for failover and
load balancing purposes. From the docs:
---------------------------------------------------------------------
You can also have multiple spamd servers to improve
scalability. These can also reside on other hardware reachable
over the network. To specify multiple spamd servers, just put
multiple address/port pairs in the spamd_address option,
separated with colons:
spamd_address = 192.168.2.10 783 : 192.168.2.11 783 : 192.168.2.12 783
Up to 32 spamd servers are supported. The servers will be
queried in a random fashion. When a server fails to respond
to the connection attempt, all other servers are tried
until one succeeds. If no server responds, the "spam"
condition will return DEFER. IMPORTANT: It is not possible
to use the UNIX socket connection method with
multiple spamd servers.
---------------------------------------------------------------------
Multiple malware scanners are not yet in, this is a bit more complicated.
CHANGELOG:
------------------------------------------------------------
20 - added option to use multiple spamd servers, both for
failover and load balancing purposes.
- Fix signal handlers when using popen() for cmdline
malware scanners.
- adapted patch to exim 4.33
