ASK is a spam killer. This program (Active Spam Killer, or ASK for short) takes an "Active" approach in solving the problem: Everytime an email is received, a message is sent back to the sender asking for confirmation. If that sender does not confirm the message, it remains queued for delivery. If the sender confirms, the message is delivered and removed from the queue. The "confirmed" senders will be added to your "whitelist" and will never be sent another confirmation. Messages from these emails will always be delivered immediately . You can also specify an "ignorelist" for emails that should be always ignored and a "blacklist" that will cause a nastygram to be sent back to the sender everytime an email is received.

There are many traditional approaches to avoiding spam. The most common approach is based on "content-filtering": a program that attempts to classify incoming mails based on their content. This works partially, but in reality, its somewhat easy to find ways to avoid it.

ASK takes advantage of the fact that most spammers use invalid or fake "From:" address in their messages. When a new message arrives and the sender is unknown, ASK sends a "confirmation message" back, informing the sender that the original message has been queued, pending confirmation. When the sender confirms (a simple reply), ASK delivers the original message and adds the sender to a "whitelist". Further messages from this sender will be immediately delivered. It is also possible to ignore messages based on specific criteria, like senders email, subject and so on.

The goal of ASK is to block Spam mail before it is delivered to your mailbox. As we know, filtering alone is not effective since many times Spam mail contains no detectable elements.

ASK should be invoked from .forward (or .procmailrc if you are using procmail). The incoming message should be piped to ASK, which will be in charge of doing the actual delivery.

When ASK receives an email, if first checks the email address against your "ignorelist". If the address is listed there, its ignored completely. Then, the message is checked against your "blacklist". If its there, a nastygram is sent back to the sender with something like "Please stop sending me emails" in the Subject line.

The real fun happens when an email comes from an unknown user (i.e, someone not in any of your lists). In this case, ASK calculates the MD5 checksum of the message + a secret MD5 key (configured during installation time). This number is sent as part of a "confirmation message" back to the user. If the user replies to it, the confirmation number (in the subject) is recognized, the message is dequeued and delivered. If the user does not reply, the message remains queued until its removed.

The program has some intelligence to deal with specific cases. For instance, if a mail is sent to a non-existing user, the error message from mailer-daemon is ignored. This avoids seeing lots of "invalid user" messages in your inbox.

Another interesting "twist" is that messages coming from your own email address are never trusted. If the spammer knows your address he could easily fake your own address as the From: line. Messages coming from you will be identified by a "mailkey", a piece of string you always put on your message by default (maybe a piece of your own signature). Note that this has the added side-effect of allowing any messages coming in reply to a message you sent to someone (as long as that person keeps your "mailkey" in its quoted reply, a practice common these days).

The program never deletes any messages. For instance, if you send yourself a message without your mailkey (a possible Spam), it will be saved in a "Junk" mailfolder (you can specify this folder during the configuration).

SMSSender is an application for sending SMS messages.

It provides a user interface with a drop-down list of available cell phone carriers and text areas for the telephone number, subject, and SMS body.

Secure Messaging is a Web-based, alternative mail system for sending and receiving messages.

Use secure messaging to send and receive messages from a alternative web-based mail system. Using the secure messaging system no actual mail is transmitted through any 3rd party servers.

Only an optional message notice is sent to the recepient, the user needs to visit the site in order to read the message.

Normal SMTP mail can hit multiple servers and can possibly be read, stored, or changed anywhere within the process.

Setup secure messaging on an SSL enabled website to enhance the privacy even more.

Mgetty+sendfax is a collection of programs to send and receive faxes in a unix environment using a class 2.0 or 2 (theyre different) faxmodem. vgetty is an extension to mgetty, distributed with it, that implements incoming voice call handling for certain voice-capable modems, with new ones added regularly, if specs are available.
More specifically, the program `mgetty allows you to use a class 2.0 or 2 fax modem for receiving faxes and handling external logins without interfering with outgoing calls.
`sendfax is a standalone program which sends fax files. `vgetty is an extended version of mgetty that can answer the telephone like an answering machine and record a voice-mail message (if it finds one), or perform `mgettys fax or data call handling otherwise.
The mgetty+sendfax distribution includes vgetty and a good-sized gob of utility programs that help you manage faxes and voice messages.
Main features:
- send faxes directly or using shell scripts (easily integrated into other applications).
- do "fax polling", this means you can call the weather station and get them to send you a fax containing the current weather map. (Not all modem manufacturers implement this feature in their modems!)
- create a "fax queue", outgoing faxes get sent automatically, the user is informed by mail about the result.
- `mgetty allows you to use a single modem line for receiving calls and dialing out.
- `mgetty knows about "smart" modems, and will make sure that the modem is always in a defined state (specific modem initialization possible)
- Incoming calls are answered manually (`RING -> `ATA -> `CONNECT) instead of using auto-answer (`ATS0=1), this way the modem wont pick up the phone when the machine is down or logins are not allowed. (but see note below for ISDN/digital modems)
- mgetty completely replaces getty and/or uugetty. Like uugetty, supports lock files in a fashion compatible with almost all known versions of UUCP (HDB/BNU, SVR4, V7, Taylor in various flavours). uugetty has some features mgetty doesnt support; see "How does mgetty differ from uugetty?" below.
- mgetty supports System V style gettydefs terminal configurations.
- mgetty can receive class 2 faxes (if your modem supports it).
- mgetty knows about incoming FidoNet calls.
- mgetty has extensive logging / debugging features
- do "fax poll sending", that is, you can setup your machine as fax poll server, to send some fax pages to "fax poll" callers. (Send informations about your system, the current wheather map, ...). Be warned, even less modems support this feature.
- mgetty can selectively refuse calls based upon CallerID, if your modem supports it, and youre subscribed to the service. CallerID is also logged.
- mgetty has facilities to allow you to refuse incoming FAXes when available disk space is low.
- mgetty knows about incoming PPP calls, and can hand them off to the PPP-daemon, without requiring a login/password sequence. This feature is also known as AutoPPP
- behaves like a normal answering machine for human callers
- automatic fax reception when a T.30 calling tone is detected
- If the caller isnt a human or fax, a data connect is attempted, if this is successful, the caller will get a normal login
- does not interfere with dialouts
- remote playback of messages via a DTMF code
- toll saver -- if there are new messages, pick up the phone earlier, this way you can hang up in time to avoid a useless call
- message light - the autoanswer LED of your modem (if it has one) is turned on if there are new messages
- easy playback - on some modems, you can play back the new messages just by pressing DATA/VOICE
- using a speech synthesizer is possible - add the date and time to messages (not included by default). The scripts show how to use a speech synthesizer like rsynth, but it is not included in the package. To use this feature, you need a voice modem for that; a converter from the pvf format to the rmd (raw modem data) format exists. This is not true for all supported modems.
- voice conversion utilities - play messages on /dev/audio (Not for all supported modems, some voice modems use a proprietary format)
- and more, more features available through the voice library/mvm
Enhancements:
- This release adds class 1/1.0 fax reception (still considered experimental).
