ClearOS is an integrated network server gateway solution for small and distributed organizations. The software provides all the necessary server tools to run an organization including email, anti-virus, anti-spam, file sharing, groupware, VPN, firewall, intrusion detection/prevention, content filtering, bandwidth management, multi-WAN, and more. You can think of it as a next generation small business server. Through the intuitive Web-based management console, an administrator can configure the server software along with integrated cloud-based services.
dgrey is a greylisting policy server that allows greylist information to be synchronized between multiple mail servers. All information is shared between the nodes and the nodes are equal; there is no master. The nodes may lose communication for a while and still be able to correctly resynchronize later. This works because all nodes keep a log of changes to the database. All communication is done across TCP connections, which can optionally be password protected. dgrey works with mail transfer agents such as Postfix and Exim.
mailprocd is a standalone mail classification and delivery daemon for massive multiuser servers, designed to extend the capabilities of MTAs such as Postfix and sendmail. It embeds perl in C in order to use SpamAssassin efficiently. It implements a process manager with persistent spam checker processes running under users' own UIDs.
GNU parallel is a shell tool for executing jobs in parallel locally or using remote computers. A job is typically a single command or a small script that has to be run for each of the lines in the input. The typical input is a list of files, a list of hosts, a list of users, a list of URLs, or a list of tables. If you use xargs today you will find GNU parallel very easy to use, as GNU parallel is written to have the same options as xargs. If you write loops in shell, you will find GNU parallel may be able to replace most of the loops and make them run faster by running several jobs in parallel. If you use ppss or pexec you will find GNU parallel will often make the command easier to read. GNU parallel makes sure output from the commands is the same output as you would get had you run the commands sequentially. This makes it possible to use output from GNU parallel as input for other programs.
Textmail filters a mail message or mbox, replacing MS Word, MS Excel, HTML, RTF, and PDF attachments with the plain text contained therein. By default, the following attachments are also deleted: image, audio, video, and MS Windows executables. MS winmail.dat attachments are replaced by any attachments contained therein, which are then replaced by text or deleted in the same fashion. Any of these actions can be suppressed with the command line options. Mail headers can also be selectively deleted.
PDFassassin is a module for SpamAssassin that allows for the scanning of PDF files in email message attachments. Email bodies are scanned upon connection and checked for PDF attachments. Text is extracted from the PDF via pdftotext and scanned by SpamAssassin. Should the PDF contain images, the gocr program is called to extract the text content. The total spam score of the PDF is compared against the global required_score setting; if it's higher, a score equal to the one specified in pdf.cf is appended to the overall score of the email message.
a2pdf converts plain (ASCII) text files to documents in the PDF format. Its features include optional line/page numbering, multiple font support, syntax highlighting for Perl source code, and customizable headers and footers. Binaries are available for Linux x86, Mac OS X (Intel), and Microsoft Windows platforms.
