Free temporary file software for linux

Disposable Temporary E-mail project provides the user with disposable e-mail addresses which expire after a certain time. The user can read and reply to e-mails that are sent to the temporary e-mail address within the given time frame.
Main features:
- Users can generate e-mail addresses
- Users can see their incoming e-mails
- Users can reply to e-mails
- Completely template driven
- Installation routine
How the script works:
With a click on a button the user generates a new e-mail address. That address will be stored in the database along with its creation time. The e-mail address is assigned to the user by a session cookie.
The user then uses the e-mail for any purpose where an e-mail address is required. Most commonly that will be some kind of registration.
In the background the script checks continuously for arriving e-mails. Once an e-mail that has been sent to a generated e-mail address arrives, the script displays it.

perlfilter package contains Perl source filters.

This article is about a little-known feature of Perl called source filters. Source filters alter the program text of a module before Perl sees it, much as a C preprocessor alters the source text of a C program before the compiler sees it. This article tells you more about what source filters are, how they work, and how to write your own.

The original purpose of source filters was to let you encrypt your program source to prevent casual piracy. This isnt all they can do, as youll soon learn. But first, the basics.

CONCEPTS

Before the Perl interpreter can execute a Perl script, it must first read it from a file into memory for parsing and compilation. If that script itself includes other scripts with a use or require statement, then each of those scripts will have to be read from their respective files as well.

Now think of each logical connection between the Perl parser and an individual file as a source stream. A source stream is created when the Perl parser opens a file, it continues to exist as the source code is read into memory, and it is destroyed when Perl is finished parsing the file. If the parser encounters a require or use statement in a source stream, a new and distinct stream is created just for that file.

The diagram below represents a single source stream, with the flow of source from a Perl script file on the left into the Perl parser on the right. This is how Perl normally operates.

file -------> parser

There are two important points to remember:

Although there can be any number of source streams in existence at any given time, only one will be active.

Every source stream is associated with only one file.

A source filter is a special kind of Perl module that intercepts and modifies a source stream before it reaches the parser. A source filter changes our diagram like this:

file ----> filter ----> parser

If that doesnt make much sense, consider the analogy of a command pipeline. Say you have a shell script stored in the compressed file trial.gz. The simple pipeline command below runs the script without needing to create a temporary file to hold the uncompressed file.

gunzip -c trial.gz | sh

In this case, the data flow from the pipeline can be represented as follows:

trial.gz ----> gunzip ----> sh

With source filters, you can store the text of your script compressed and use a source filter to uncompress it for Perls parser:

compressed gunzip
Perl program ---> source filter ---> parser

Tmpf is tiny script (written in Ruby) to write standard output to a temporary file, run an application with the name of that file as an argument, then delete the temporary file when done.

The project is useful when you want to pipe output to a program that only accepts files, not standard input. Example: cat myfile.ps | tmpf gv (equivalent to: gv myfile.ps). Despite the incredible simplicity of this script, there is nothing quite like it provided among the standard Unix tools.

smf-clamd is a Sendmail milter for the ClamAV (Clam AntiVirus).
Sendmail filter for ClamAV aims to be lightweight, reliable and simple. Sendmail filter for ClamAV is written in C.
Main features:
- It has a hosts/networks whitelist;
- It can scan messages less than a defined size only;
- It rejects infected messages at the SMTP DATA stage;
- It can add an information header with scan results to scanned messages;
- It can log all milter activities through the syslog service.
Advantages:
- Small code;
- Fast work;
- Stability (production quality);
- Few system resources are required;
- No temporary files are created.
Enhancements:
- A workaround for the Sendmail socket unsafe error on some platforms was implemented.
- Clean email messages logging was removed.
- Configuration file, default user, and working directory were changed.
- The format of log records was changed.
- Some samples of start-up scripts were added.
- The new TODO tasks were added.
- Cosmetic enhancements were made.

check_writable is a Nagios plugin that checks if one or more directories are writable by checking that the supplied directory is indeed a directory, checking if the the filesystem permissions are OK, creating a temporary file, writing random data to the temporary file, and reading it back.

It returns a critical status if one of the tests fails.

Spamavert.com provides an extension which allows you to easily register on this website.

Generates temporary e-mail addresses for all those pesky online registration forms using the free spamavert.com service.

Highly customizable and easy to use.

smf-spamd is a Sendmail filter for SpamAssassin. Sendmail filter for SpamAssassin aims to be lightweight, reliable, and simple rather than have a myriad of options.
It only scans the messages less than defined size, has a hosts/networks whitelist, performs subject tagging if SPAM is detected, adds an information header, copies SPAM messages to the defined "garbage" mailbox, rejects SPAM messages at the SMTP DATA stage, and logs all filter activities to syslog.
The code is small (does not exceed 580 lines), fast, stable, and few resources are required. No temporary files are created.
Main features:
- It has a hosts/networks whitelist;
- It can scan messages less than a defined size only;
- It can tag the Subject if SPAM has been detected;
- It can add an information header with scan results to scanned messages;
- It can copy SPAM messages to the special "garbage" mailbox;
- It rejects SPAM messages at the SMTP DATA stage, if SPAM score is greater than a defined value;
- It can log all milter activities through the syslog service.
Advantages:
- Small code;
- Fast work;
- Stability (production quality);
- Few system resources are required;
- No temporary files are created.
Enhancements:
- Incorrect handling of missed Message-Id: header was fixed.
- Cosmetic enhancements were made.
