Free postfix 2.4.5 software for linux

Postfix project is Wietse Venemas mailer that started life as an alternative to the widely-used Sendmail program.

Postfix attempts to be fast, easy to administer, and secure, while at the same time being sendmail compatible enough to not upset existing users. Thus, the outside has a sendmail-ish flavor, but the inside is completely different.

Postfix-policy is a policy server that uses ServerKit to achieve a high level of performance and scalability for Postfix servers.

This project is ideal for use with large mail systems utilizing Postfix for MX duties and MySQL for the management of accounts with basic policy needs.

Usage:

It is advised that you read the ServerKit documentation before trying to use this module, as most of the basic usage is simply using ServerKit, nothing specific to this module.

You will probably want to use the included ServerKit personality as a starting point, found in the source archive as a directory named "personality". Within the personality you will find a "c11n" file, a "modules" subdirectory, and a "svsdir" subdirectory.

The "c11n" file is a ServerKit configuration file, you will need to at least modify the database settings so ServerKit can successfully communicate with your database system. Another configuration value that you will definitely have to set is "action_query_format_string".

The "action_query_format_string" is the SQL query postfix-policy will use to retrieve an action to send back to Postfix in response to policy delegation requests. See the Configuration section for a list of supported substitutions for use in the format string.

You are responsible for creating a query that is compatible with your mail system database schema, and ensuring that the query will:

1. return an empty set for invalid recipients
2. return a valid action string when not returning an empty set

For an explanation of valid policy action responses, see the access(5) manual reference from Postfix, youre interested in the *ACTIONS sections

LoFiMo is used to monitor logfiles in real time. The output is presented via a web interface and optionally on the console.
Using the web interface it is possible to monitor log files from a remote machine. LoFiMo can be used to colorize the log entries using filters.
Filters can also be used to reformat log entries, hide log entries or play sounds or execute commands when certain log entries are read.
LoFiMo uses inputs to read log entries from different file formats. It can for instance parse files created by the syslog daemon or the apache web server.
Main features:
- Support for apache style log files
- Support for syslog style log files
- Can process iptables log and reformat it. Can detect most ICMP types and convert them to cleat text.
- For example
- Nov 23 16:53:32 esme kernel: FW_ACCEPT: IN=eth1 OUT=eth0 SRC=x.x.x.x DST=x.x.x.x LEN=84 TOS=0x00 PREC=0x00 TTL=53 ID=12419 PROTO=ICMP TYPE=0 CODE=0 ID=7220 SEQ=7
- can be transformed into:
- Nov 23 16:53:32 esme kernel: FW_ACCEPT: ICMP / eth1->eth0 / x.x.x.x->x.x.x.x / len=84 / tos=0x00 / Echo Reply / ttl=53
- Can process postfix mail entries and output them as single line per mail.
- For example these seven lines
- Nov 23 17:56:01 magrat postfix/smtpd[13644]: connect from mx02.domain.com[x.x.x.x]
- Nov 23 17:56:01 magrat postfix/smtpd[13644]: A297015B603: client=mx02.domain.com[x.x.x.x]
- Nov 23 17:56:01 magrat postfix/cleanup[13648]: A297015B603: message-id=< 002d01c5f04e$c44f16c0$0100a8c0@eva >
- Nov 23 17:56:02 magrat postfix/qmgr[2764]: A297015B603: from=< send@domain.com >, size=170113, nrcpt=1 (queue active)
- Nov 23 17:56:10 magrat postfix/smtp[13649]: A297015B603: to=< rec@domain.com >, relay=localhost[127.0.0.1], delay=9, status=sent (250 2.6.0 Ok, id=12734-02, from MTA: 250 Ok: queued as 1508615B633)
- Nov 23 17:56:10 magrat postfix/qmgr[2764]: A297015B603: removed
- Nov 23 17:56:32 magrat postfix/smtpd[13644]: disconnect from mx02.domain.com[x.x.x.x]
- can be transformed into a single line:
- 2005-11-23 17:56:10 magrat postfix send@domain.com -> rec@domain.com / mx02.domain.com[x.x.x.x] -> localhost[127.0.0.1] / 9 sec / 170113 bytes / sent (250 2.6.0 Ok, id=12734-02, from MTA: 250 Ok: queued as 1508615B633)
- Can remove unwanted log entries from the output.
- Can set the style for each field of a log entry using css allowing multiple fonts and colours in the same line.
- Can play a sound whenever a log entry matching certain criteria is read (e.g. when mail from a certain sender arrived).
- Can execute a command whenever a log entry matching certain criteria is read (e.g. to send an email or play sound using a custom sound player).
- Filters use regular expressions to match certain fields or the entire log entries.
- Can process log files of any format.
- Access via web browser from remote machines. View the log entries as they are read in real time or browse and refresh the output in the interval you configure.
Enhancements:
- The character set of monitored files can now be specified.
- Filenames in the execute property of filters can now contain blank characters.

Postgrey is a Postfix policy server implementing greylisting.

When a request for delivery of a mail is received by Postfix via SMTP, the triplet CLIENT_IP / SENDER / RECIPIENT is built. If it is the first time that this triplet is seen, or if the triplet was first seen, less than 5 minutes ago, then the mail gets rejected with a temporary error. Hopefully spammers or viruses will not try again later, as it is however required per RFC.

Safe database:

greylist.pl doesnt lock correctly the database and it might get corrupted after a while (two days mean time for me). Postgrey does use the logging and transaction features of BerkeleyDB to maximize reliability. Additionally only one process is running, thus reducing even more the risk of corrupting the database.

Automatic maintenance:

Postgrey does keep track not only of the first time a given triplet was seen, but also the last time. Entries that were last seen more than a defined amount of time ago (one month for example) get removed automatically.

Whitelists:

Per-client and per-recipient whitelists. The Postgrey distribution package includes a client whitelist with all (few) broken mail-servers that were identified until now.

Lookup by subnet:

Addresses are normally stripped of their last byte, so that mail servers with multiple addresses are recognized as only one.

Auto-whitelisting of clients:

Clients which repeatedly show to be able to pass the greylist, are entered in a "clients whitelist", for which no greylisting is done anymore.

OCSID is a Slackware based distro with Gnome, like the good old Slackware used to have.
First lets start with what OCSID is NOT:
- is not yet another linux distro;
- is not yet another fork;
- is not born to divide the Community;
- is not a closed development project.
So What OCSID really is?
- is a wrapper to contain official Slackware packages together with Community related efforts;
- is a Slackware based distro with Gnome, like the good old Slackware used to have;
- is an installation dvd so that you can install everything you want from the good old Slackware installer;
- is an open Community project and everyone is free to participate, the first goal is to unite Slackware Communitys efforts.
So OCSID is a dvd with all the Official Slackware packages untouched, with Freerock GNOME and some other packages that usually people want but arent included in Slackware (Amarok, Postfix, ecc.). Besides OCSID ships kernel 2.6.13 by default.
Not only you can install everything from the classic installer but also OCSID fully supports dependencies through slapt-get.
So that you can do it the debian way: install a minimum set of packages directly from the first Slackware CD, then install slapt-get and set OCSID as your main repository, finally you can get everything you need as in this example:
slapt-get --install kde
This way you can also upgrade your old Slackware system to OCSID with a single command.
Latest stable version of OCSID: 10.2 (Slackware 10.2, Freerock GNOME 2.12.1).

Logcheck parses system logs and generates email reports based on anomalies. Anomolies can be defined by users with violations files.
It differentiates between Active System Attacks, Security Violations, and Unusual Activity, and is smart enough to remember where in the log it stopped processing to improve efficiency.
Logcheck project can also warn when log files shrink, and does not report errors when they are rotated.
Enhancements:
- This release includes pacakging and documentation changes.
- Rulefile updates were done for smartd, sudoedit, dhcp, ipv6, openssh, oidentd, pdns, xinetd, saslauthd, postfix, spamassassin, dkfilter, anacron, dovecot, kdm, nagios, sympa, stunnel, squid, rsync, rsnapshot, proftpd, ntp, Linux kernel, cron, cron-apt, pppd, and squidguard.
