Hello again,

I strongly reccomend using the Postfix grey-listing policy service presented here Sqlgrey in order to increase the rate of spam email messages filtering. I use this this service since 2 years and it dramatically decrease(together with cbl's) the rate of inbox delivered spam.

Almost all software requirements are fulfilled by current SMS Native CD.
There still are needed the following perl modules which are very easy to compile: Net::Server; IO::Multiplex; and at least one or all of DBD::Pg; DBD::SQLite; DBD::mysql(my option) in order to build/access the database.

I have built&test a package which I'll be glad to share for a stronger SMS.

Regards.

With pleasure:

A. The builds are here: txz, tgz and the txt.

B. Compiled by elements: sqlgrey_only, Net::Server & IO::Multiplex, sqlite module, mysql module.

Notes:
1. In order to enable sqlgrey service, it is still necessary to make executable and launch somehow(rc.M) rc.sqlgrey(in /etc/rc.d) and to manually add in postfix's main.cf, as the last recipient restriction:
Code:
smtpd_recipient_restrictions =
permit_mynetworks,
......
reject_rbl_client zen.spamhaus.org,
.......
check_policy_service inet:127.0.0.1:2501

2. This build is made to use a mysql database. Using a sqlite database is (more)simpler but not as fast and as easy to control.
3. No other(perl) DBI or DBD modules are needed as I said before, because SMS allready include them.

I'll be happy to share further help if needed.

Thanks
I made some modifications to install script to be able someone to pick his own password for db, and added var/log/packages with IO-Multiplex and Net-Server to be upgradable.
Your package says version 1.7.8, I only found 1.6.8 and 1.7.6 in their site, also usr/sbin/sqlgrey says 1.7.6.

I'm glad I could make a usefull sugestion. I personally am very satisfied after using this package for a long time, it kept away a lot of spam.

It is my mistake about the version numbers, I started with 1.6.8 as they say it is the stable release, but after reading a lot of user opinions, I found that 1.7.6 works also very good, so I switched the 7 but not the 8.

Regards.
