Free mailserver uni rostock software for linux

MailRecon is Unix email content control application. It does listen network traffic, capture SMTP messages, analyse it (checks against very flexible and extendable checklist), discards usual private/business messages and save suspicious messages for detailed inspection by security staff.
Main features:
- Capturing email messages from the wire. So its compatible will all mailing software, do not require any reconfiguration and captures messages even if its sent directly to recipient bypassing your mailserver.
- Support for SMTP and POP3 protocols.
- Very flexible mailing filter which goes with MailRecon allows to record only suspicious messages which worth to be examined, and skip usual private and business messages.
- Open Architecture. MailRecon supports plugins for analysis and save of messages. Its very easy to extend its functionality with new plugins - every programmer and system administrator can write it.
- Thanks to Open Architecture, you can use your favorite mail reader or browser to manage archive of captured suspicious messages.
- For limited time, WWW-Security offers free installation and support of evaluation versions on your servers.
- FREE evaluation version which is never expires!
Installation:
- Create user mailrecon and groups mailrecon and mail
- From installation directory run "make install" (as root)
- Copy init.d/mailrecon to your init.d directory and optionally create symlinks from rcN directories if you want to automatially start mailrecon on boot.

Fetchmail is a full-featured, robust, well-documented remote-mail retrieval and forwarding utility intended to be used over on-demand TCP/IP links (such as SLIP or PPP connections). Fetchmail supports every remote-mail protocol now in use on the Internet: POP2, POP3, RPOP, APOP, KPOP, all flavors of IMAP, ETRN, and ODMR. It can even support IPv6 and IPSEC.
Fetchmail retrieves mail from remote mail servers and forwards it via SMTP, so it can then be read by normal mail user agents such as mutt, elm(1) or BSD Mail. It allows all your system MTAs filtering, forwarding, and aliasing facilities to work just as they would on normal mail.
Fetchmail offers better security than any other Unix remote-mail client. It supports APOP, KPOP, OTP, Compuserve RPA, Microsoft NTLM, and IMAP RFC1731 encrypted authentication methods including CRAM-MD5 to avoid sending passwords en clair. It can be configured to support end-to-end encryption via tunneling with ssh, the Secure Shell.
Fetchmail can be used as a POP/IMAP-to-SMTP gateway for an entire DNS domain, collecting mail from a single drop box on an ISP and SMTP-forwarding it based on header addresses. (We dont really recommend this, though, as it may lose important envelope-header information. ETRN or a UUCP connection is better.)
Fetchmail can be started automatically and silently as a system daemon at boot time. When running in this mode with a short poll interval, it is pretty hard for anyone to tell that the incoming mail link is not a full-time "push" connection.
Fetchmail is easy to configure. You can edit its dotfile directly, or use the interactive GUI configurator (fetchmailconf) supplied with the fetchmail distribution. It is also directly supported in linuxconf versions 1.16r8 and later.
Fetchmail is fast and lightweight. It packs all its standard features (POP3, IMAP, and ETRN support) in 196K of core on a Pentium under Linux.
Fetchmail is open-source software. The openness of the sources is your strongest possible assurance of quality and reliability.
Main features:
- STARTTLS is supported in both POP and IMAP.
- ESMTP AUTH (RFC 2554) is supported.
- Has the capability of adding trace information to the Received header to faciliate mail filtering by mailserver and remote account.
- Fetchmail now has options to handle SSL certificate validation.
- Fetchmail can be told to fall back to delivering via local sendmail if it cant open port 25.
- Support for AUTH=CRAM-MD5 under POP3, a la RFC2195.
- Support for ODMR (On-Demand Mail Relay), RFC 2645.
- Its now easy to deliver mail to a local LMTP socket.
- The interface option now checks both local and remote interface IPs.
- The plugin facility has been enhanced; %h and %p options are now available to pass in the hostname and service port number.
- Added a dropdelivered option to discard Delivered-To headers. This addresses a problem with using fetchmail and postfix as a relay inside a domain; when postfix sees incoming messages with delivered-to headers looking exactly the same as the ones it adds himself, it bounces the message.
- Added --smtpname to set username and domain portion of SMTP "RCPT TO" command. - Added "from" servers IP address to inserted Received line.
- Fetchmail now runs on BeOS, thanks to David Reid .
- In IMAP, unseen-message counting and indexing is now done by SEARCH UNSEEN at the beginning of each poll or re-poll (rather than with the UNSEEN and RECENT responses and FLAGS queries on individual messages). This significantly cuts down on traffic to and from the server, and gives more reliable results.
- The aka option now matches hostname suffixes, so (for example) saying `aka netaxs.com will match not just netaxs.com but also (say) pop3.netaxs.com and mail.netaxs.com.
- Fetchmail can optionally use the RFC 2177 IDLE extension on an IMAP server that supports it. On IMAP servers that dont, it can simulate it using periodic NOOP commands.
- Fetchmail now recognizes the RFC 2449 extended responses [IN-USE] and [LOGIN-DELAY].
- Fetchmail running in daemon mode now restarts itself quietly when the rc file is touched.
- Following recent court decisions and changes in U.S. federal regulatory policy, hooks for Secure Sockets Layer (SSL) are now part of the main fetchmail distribution. The distribution still contains no actual cryptographic code.
- NTLM support under IMAP, so fetchmail can query Microsoft Exchange servers.
- Expunge option can now be used to break POP3 retrieval into subsessions.
- Support for AUTH=CRAM-MD5 under IMAP, a la RFC2195.

lfwmail is a light weight web mail program written in perl.
It will run with acceptable speed even on a Pentium 100Mhz Linux mailserver.
It has just basic features and no calendar or folders but it is fully
mime compatible and can handle attachments.
If you dont like browser cookies, this program is very suitable for you, because you dont have to enable cookies.
It is also very secure when you use https (encryption). HTML
mails are converted to ASCII text for security reasons but
you can still see the HTML mail if you want.
The code is clean and structured. Installation is straight forward
and you dont need a lot of non standard modules.
You can run it in mod_perl if you want. Remember to restart the
server when you do changes in the lfwmC.pm or any other file.
Response time will be very fast with mod_perl however for most people
normal cgi-bin will be good enough. lfwmail is already quite fast.
lfwmail is a light weight mail program. It does not keep track on what
you have read and what is new. You have to remember the dates of the
mails. There is however a small help to keep track on what you have seen
and what is new. It works for Mozilla (not netscape 4), Opera and MS IE
only as it depends on javascript style objects: the background color of e-mails
you have clicked on is changed. This is to keep track on what you have
read and what is new. This information does also survive between sessions since
version 1.5.
Enhancements:
- make it possible to call lfwmail with uid=xxx in the url. e.g https://my.host/cgi-perl/lfwmail?uid=joe_wm

Array::Iterator is a simple class for iterating over Perl arrays.

SYNOPSIS

use Array::Iterator;

# create an iterator with an array
my $i = Array::Iterator->new(1 .. 100);

# create an iterator with an array reference
my $i = Array::Iterator->new(@array);

# create an iterator with a hash reference
my $i = Array::Iterator->new({ __array__ => @array });

# a base iterator example
while ($i->hasNext()) {
if ($i->peek() < 50) {
# ... do something because
# the next element is over 50
}
my $current = $i->next();
# ... do something with current
}

# shortcut style
my @accumulation;
push @accumulation => { item => $iterator->next() } while $iterator->hasNext();

# C++ ish style iterator
for (my $i = Array::Iterator->new(@array); $i->hasNext(); $i->next()) {
my $current = $i->current();
# .. do something with current
}

# common perl iterator idiom
my $current;
while ($current = $i->getNext()) {
# ... do something with $current
}

This class provides a very simple iterator interface. It is is uni-directional and can only be used once. It provides no means of reverseing or reseting the iterator. It is not recommended to alter the array during iteration, however no attempt is made to enforce this (although I will if I can find an efficient means of doing so). This class only intends to provide a clear and simple means of generic iteration, nothing more (yet).

Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other.
Unison shares a number of features with tools such as configuration management packages (CVS, PRCS, Subversion, BitKeeper, etc.), distributed filesystems (Coda, etc.), uni-directional mirroring utilities (rsync, etc.), and other synchronizers (Intellisync, Reconcile, etc).
Main features:
- Unison runs on both Windows and many flavors of Unix (Solaris, Linux, OS X, etc.) systems. Moreover, Unison works across platforms, allowing you to synchronize a Windows laptop with a Unix server, for example.
- Unlike simple mirroring or backup utilities, Unison can deal with updates to both replicas of a distributed directory structure. Updates that do not conflict are propagated automatically. Conflicting updates are detected and displayed.
- Unlike a distributed filesystem, Unison is a user-level program: there is no need to modify the kernel or to have superuser privileges on either host.
- Unison works between any pair of machines connected to the internet, communicating over either a direct socket link or tunneling over an encrypted ssh connection. It is careful with network bandwidth, and runs well over slow links such as PPP connections. Transfers of small updates to large files are optimized using a compression protocol similar to rsync.
- Unison is resilient to failure. It is careful to leave the replicas and its own private structures in a sensible state at all times, even in case of abnormal termination or communication failures.
- Unison has a clear and precise specification.
- Unison is free; full source code is available under the GNU Public License.

PHPwebmail is a Web-based IMAP and SMTP mail client. Often it is not possible to make outside mail connections from networks behind strict firewalls, or to configure a regular mail client (for example in an Internet cafe).

With PHPwebmail a mail client only needs a WWW connection to the mailserver. Specifically it only needs a connection to the webserver hosting PHPwebmail.

Most of the times the Web and mail server will be the same machine but PHPwebmail can connect to other mailservers as well as long as an IMAP connection between these two machines is allowed.

For those who want to build their own mailserver from sources on different GNU/Linux distributions like Slackware, Gentoo, CentOS, SuSe, Fedora Core or Debian, we created an universal package called qinstall-src.
qinstall-src is a source package collection along with a bash script that helps an administrator to compile, configure, install and run an e-mail server, based on qmail, together with all the programs required to run properly.
Main features:
- all perl modules required for optimum runtime;
- user administration web interface(qmailadmin);
- console-based user and domain administration (vpopmail, cqadmin);
- a bash script that eases the administration of queue pending messages (qmHandle);
- personalized webmail (SSL/TLS), activated quota, password changer (squirrelmail);
- ESMTP/SMTP, IMAP/POP3 SSL services activated by default (qmail, courier imap);
- e-mail autoresponder (autorespond);
- antivirus and antispam software (clamav, spamassassin);
- email filters (procmail);
- other programs that help running the e-mail server at optimum speed;
qinstall-src is tested on Slackware, Gentoo, Fedora Core, CentOS, openSuSe and Debian.
Enhancements:
- Many packages have been upgraded to the latest version.
- All packages have been ported to Bluewhite64 Linux (64-bit).
