Free qmail queue software for linux

Qmail Auditor consists of a email auditing tool.
QMail Auditor provides simple a method for auditing emails. It is easy to configure and uses regular expressions as rules.
The format of audit file is :
Any e-mail (outbound or inbound) have passed at this filter.
The valids "field header"(s) :
all - field from or to of e-mails
to - field to
from - field from
In case of regular expression you read the
# man re_format
# man regex
E-mail to forward is a valid mail account to redirect.
Example of this :
from nelio@walk.* auditoria@spyware.walk.com.br
to nelio@spyware.* auditoria@spyware.walk.com.br
Enhancements:
- Now the config file name has renamed.
- From audit (in /var/qmail/control for /var/qmail/control/auditor) and qmail-queue-real-audit for qmail-queue-real-auditor.

dirqmail is a qmail patch which adds simple and fast virtual users support based on directories.
dirqmail puts users in /var/qmail/mail/< domain >/< login > directories, so for instance if /var/qmail/mail/example.org/example directory exists, qmail will treat example.org as a local domain, will accept mail for it via SMTP and QMTP daemons and will deliver mail to example@example.org as alias user using /var/qmail/mail/example.org/example as the home directory.
Main features:
- simple - you can just "see" and administer your domains and users from the command line or any file manager
- fast - checking for user of domain existence is just stating the correct directory
- atomic - all changes do not need any restarts/etc - everything just work in the "real-time"
- simple and fast aliases - just use symbolic links!
- works out of the box - just create /var/qmail/mail/domain.org/user to create user@domain.org user - permissions, ownership and Maildir creation will be handled automatically
- does not remove any of qmail features - dirqmail can coexist with any existent qmail installation - for example you can have some domains and users handled by system users (using /etc/passwd), some by qmail-users (/var/qmail/users), some by vpopmail and some by dirqmail (/var/qmail/mail)
- includes patch for checkpassword with support for POP3 (PASS and APOP) and SMTP (LOGIN, PLAIN, CRAM-MD5) - both for Krzysztof Dabrowskis and Erwin Hoffmanns SMTP AUTH patches

qmail-spp adds plugin support to qmails SMTP daemon (qmail-smtpd). qmail-spp is written entirely in C using native qmail libraries, so it does not create any dependencies.
qmail-spp has been written because currently there is no common way of enhancing qmail-smtpds functionality apart of patches which usually are not compatible one with other and require recompilation.
In addition, qmail-spp gives you possibility of enhancing your mail server in any language, so you can easily integrate it with anything you want.
Plugins are external programs which are executed after processing SMTP command, but just before accepting it by qmail; this lets you to add extra checks on commands arguments before accepting it; for instance you can check envelope recipient address against your "black list".
Plugins can be written in any language, because they are independent programs. They:
- should not read anything from standard input,
- should not exit with error code 120,
- should print all errors to standard error (they are logged),
- can print commands on standard output.

Parallel::Queue is a Perl module to fork or thread a list of closures N-way parallel.

SYNOPSIS

# example queue:
# only squish files larger than 8KB in size. figure
# that the system can handle four copies of squish
# running at the same time without them interfering
# with one another.

my @queue = map { -s > 8192 ? sub{ squish $_ } : () } @filz;

# functional: pass in the count and list of coderefs.
#
# adding runqueue exports the subroutine into
# the current package. useful for non-OO situations.
#
# run the queue 4 way parallel.

use Parallel::Queue qw( runqueue verbose fork );

my @remaining = runqueue 4, @queue;

die "Incomplete jobs" if @remaining;

# OO: generate queue manager and use without the
# runqueue arguments, construct a queue manager,
# and use it to run the jobs

use Parallel::Queue;

my $quemgr = Parallel::Queue->construct( thread );

$quemgr->runqueue( 4, @queue );

die "Incomplete jobs" if @queue;

# call Parallel::Queue with the default configuration
# (fork quietly).

require Parallel::Queue;

Parallel::Queue->runqueue( 4, @queue );

# pre-define defaults for the objects: leave
# out runqueue, set the rest, and construct
# an object. the one here gets verbose, thread,
# and debug all set to true.

use Parallel::Queue qw( verbose thread );

my $quemgr = Parallel::Queue->construct( debug );

my @remaining = $quemgr->runqueue( 4, @queue );

Given a count and an array of coderefs (most likely closures), runqueue will run the jobs in parallel. The jobs can be run via fork or detached threads [see known issues for threading]. Jobs on the queue are executed until one of them exits non-zero, the fork/thread operation fails, or all of them are dispatched (i.e., the queue is empty).

pfqueue is a console-based tool for handling MTA queues.

pfqueue is an effort to give postqueue/mailq/postsuper/exim4 a console (ncurses) interface: it wont add any particular functionality to those provided with MTAs themselves, but will hopefully make them easier to use.

Its a real-time queue scanner, that shows per-queue lists of existing messages; the messages can be shown, deleted, put on hold, released or requeued.

Just for example, it may be useful to inspect a traffic jam at a given time, to see what is falling into and unexpectedly crowding your deferred queue.

qmail-rblchk filter all incoming mail and check if it comes from RBL listed IPs.
It is for use in .qmail to check the IP address from the Received lines. qmail-rblchk has the same function as rblsmtpd, but the messages are checked at local delivery time.
Compile it with:
tar -xfz qmail-rblchk-[version].tar.gz
cd qmail-rblchk
make setup check
Edit conf-* files to set compile and install options. If you use FreeBSD you can install qmail-rblchk with his port:
cd /usr/ports/mail/qmail-rblchk
make install clean
Use
|qmail-rblchk [options] [/dir/]
qmail-rblchk is for use in .qmail to check the IP address from the Received: from lines. It has the same function as rblsmtpd, but the messages are checked at local delivery time, with this you can check the content of the message simply redirecting it to another mailbox or address.
If a directory is given with dir all spam message are delivered to that directory if it exist and is in Maildir format.
Directory name must start with a / or . (dot) and end with a /.
General options:
-h: show a sort program description;
-s: add "X-Spam" header into the incoming mail (work only with delivery in dir/);
-i NUM: ignore first NUM IPs found in the header;
-x IP: do not check IP, try to find other address in header (you can ignore max 16 IPs);
-m: check all IPs that find in mail header (default check only the first);
-v: debug mode, make output more verbose;
-p: dont check private IP classes:
127.0.0.0 - 127.255.255.255
10.0.0.0 - 10.255.255.255
172.16.0.0 - 172.31.255.255
192.168.0.0 - 192.168.255.255
-q: quiet mode;
-l LOG: redirect to file LOG program messages;
-L DATA: write blocked IP address tu file DATA (you can use the DATA file to build your RBL list, see example below);
-c: turn on the condredirect compatibility mode for exit code.
Control options
-r addr: request if a TXT record exist into addr;
-R addr: request if a TXT record not exist into addr;
-a addr: request if a A record not exist into addr;
-A addr: request if a A record exist into addr;
-C addr: request if a A or TXT record exist into addr, if true the mail is not SPAM and the program exit;
-X cdb: check if the sender IP is listed in cdb file, see tcprules or EXAMPLES section for the format
Its possible to use up to 32 control options to specify more RBL server; those are checked until the first of them answere true and the mail will be tagged as a "spam" (unless you use -C option).
If a mail come from a.b.c.d IP, the request that the program send to DNS server is: d.c.b.a.addr where addr is the parameter that come after -r, -R, -a or -A options.
Enhancements:
- This release adds many new features: CDB RBL checking, a better IP search method, better logging, and more.
