Ubuntu 15.04 Server with systemd: Administration and Reference by Richard Petersen

Amazon Web Services, bash_history, cloud computing, Debian, Firefox, lock screen, Mark Shuttleworth, MITM: man-in-the-middle, OpenAI, operational security, RFC: Request For Comment, SpamAssassin, web application

There you can find detailed documentation, FAQs, mailing lists, and even a listing of the tests that SpamAssassin performs. Note: For dovecot IMAP server you can use dovecot-antispam plugin to implement spam detection. SpamAssassin rule files are located at /usr/share/spamassassin. The files contain rules for running tests such as detecting the fake hello in the header. Configuration files for SpamAssassin are located at /etc/spamassassin. The local.cf file lists system-wide SpamAssassin options such as how to rewrite headers. The init.pre file holds spam system configurations. Server options such as enabling SpamAssassin, are listed in the /etc/default spamassassin file. Users can set their own SpamAssassin option in their .spamassassin/user_prefs file.

Add the clamav user to the amavis group to allow amavis to use clamav to scan files. sudo adduser calmav amavis sudo adduser amavis clamav Enable spamassassin by editing the spamassassin configuration file, /etc/default/spamassassin, and setting the ENABLED entry to 1. ENABLED=1 Then start spamassassin. sudo service spamassasin start You can then configure Amavisd-new using files in the /etc/amavis/conf.d directory. To activate virus detection and spamassassin, edit the /etc/amavis/conf.d/15_content_filter_mode file and uncomment the lines for virus detection and spamassassin as indicated by the comments. Ubuntu also recommends that you disable the bounce response for spam emails by settings the final_spam_destiny option in the 20_debian_defaults file to D_DISCARD instead of D_BOUNCE.

The Courier-IMAP server (http://courier-mta.org) is a small, fast IMAP server that provides extensive authentication support including LDAP and PAM (Universe repository). Spam: SpamAssassin With SpamAssassin, you can filter sent and received e-mail for spam. The filter examines both headers and content, drawing on rules designed to detect common spam messages. When they are detected, it then tags the message as spam, so that a mail client can then discard it. SpamAssassin will also report spam messages to spam detection databases. The version of SpamAssassin distributed for Linux is the open source version developed by the Apache project, located at http://spamassassin.apache.org. There you can find detailed documentation, FAQs, mailing lists, and even a listing of the tests that SpamAssassin performs.

The Debian Administrator's Handbook, Debian Wheezy From Discovery to Mastery by Raphaal Hertzog, Roland Mas

With this command, it is possible to go back to an older version of a package (if for instance you know that it works well), provided that it is still available in one of the sources referenced by the sources.list file. Otherwise the snapshot.debian.org archive can come to the rescue (see sidebar GOING FURTHER Old package versions: snapshot.debian.org). Example 6.3. Installation of the unstable version of spamassassin # apt-get install spamassassin/unstable GOING FURTHER The cache of .deb files APT keeps a copy of each downloaded .deb file in the directory /var/cache/apt/archives/. In case of frequent updates, this directory can quickly take a lot of disk space with several versions of each package; you should regularly sort through them.

A milter (short for mail filter) is a filtering program specially designed to interface with email servers. A milter uses a standard application programming interface (API) that provides much better performance than filters external to the email servers. Milters were initially introduced by Sendmail, but Postfix soon followed suit. QUICK LOOK A milter for Spamassassin The spamass-milter package provides a milter based on SpamAssassin, the famous unsolicited email detector. It can be used to flag messages as probable spams (by adding an extra header) and/or to reject the messages altogether if their “spamminess” score goes beyond a given threshold. Once the clamav-milter package is installed, the milter should be reconfigured to run on a TCP port rather than on the default named socket.

Stable Updates Stable updates are not security sensitive but are deemed important enough to be pushed to users before the next stable point release. This repository will typically contain fixes for critical bugs which could not be fixed before release or which have been introduced by subsequent updates. Depending on the urgency, it can also contain updates for packages that have to evolve over time… like spamassassin's spam detection rules, clamav's virus database, or the daylight-saving rules of all timezones (tzdata). In practice, this repository is a subset of the proposed-updates repository, carefully selected by the Stable Release Managers. 6.1.2.3. Proposed Updates Once published, the Stable distribution is only updated about once every 2 months.


Hands-On Machine Learning With Scikit-Learn, Keras, and TensorFlow: Concepts, Tools, and Techniques to Build Intelligent Systems by Aurelien Geron

You should observe that your model performs even better now! This technique of artificially growing the training set is called data augmentation or training set expansion. Tackle the Titanic dataset. A great place to start is on Kaggle. Build a spam classifier (a more challenging exercise): Download examples of spam and ham from Apache SpamAssassin’s public datasets. Unzip the datasets and familiarize yourself with the data format. Split the datasets into a training set and a test set. Write a data preparation pipeline to convert each email into a feature vector. Your preparation pipeline should transform an email into a (sparse) vector indicating the presence or absence of each possible word.

Most of the returned information has little to do with the actual text of a message. For example, the email message retrieved in Listing 15-6 doesn't appear until over halfway down the listing. The rest of the text returned by the mail server consists of headers, which tell the mail client the path the message took, which services touched it (like SpamAssassin), how to display or handle the message, to whom to send replies, and so forth. These headers include some familiar information such as the subject header, the to and from values, and the MIME version. You can easily parse this information with the return_between() function found in the LIB_parse library (see Chapter 4), as shown in Listing 15-7.

We’re going to put these classes into the os directory and also import them into our site.pp file (again, we’ve already seen this in Listing 4-1). import "os/*" In Listing 4-7, you can see both these classes. Listing 4-7. The Operating System Classes class fedora { yumrepo { "testing.com-repo": baseurl => "http://repos.testing.com/fedora/$lsbdistrelease/", descr => "Testing.com's YUM repository", enabled => 1, gpgcheck => 0, } } class debian { $disableservices = ["hplip", "avahi-daemon", "rsync", "spamassassin"] service { $disableservices: enable => false, ensure => stopped, } } In Listing 4-7, we’ve created two classes; the first is fedora, which loads whenever a node returns Fedora as the value of the $operatingsystem fact. It uses the yumrepo type to setup a yum repository for our environment. We’ve also used another fact, $lsbdistrelease, which returns the LSB release number to select the correct repository for the Fedora release we have installed.

He's worked with Debian, Ubuntu, and SUSE, but what he knows best is RHEL-based distributions. He's known for his contributions to the MailScanner project (he has been a technical reviewer for the MailScanner book), but he also gave time to different open-source projects, such as mondorescue, OTRS, SpamAssassin, pfSense, and a few others. I thank my lover, Lysanne, who accepted allowing me some free time slots for this review even with a 2-year-old and a 6-month-old to take care of. The presence of these 3 human beings in my life is simply invaluable. I must also thank my friend Sébastien, whose generosity is only matched by his knowledge and kindness.

You will have to consult your mailing list software's documentation for that (see the section called “Mailing List / Message Forum Software” later in this chapter). List software often comes with some built-in spam prevention features, but you may want to add some third-party filters. I've had good experiences with SpamAssassin (spamassassin.apache.org) and SpamProbe (spamprobe.sourceforge.net), but this is not a comment on the many other open source spam filters out there, some of which are apparently also quite good. I just happen to have used those two myself and been satisfied with them. Moderation. For mails that aren't automatically allowed by virtue of being from a list subscriber, and which make it through the spam filtering software, if any, the last stage is moderation: the mail is routed to a special holding area, where a human examines it and confirms or rejects it.

The only real issue with the OCamlMakefile is that you need more than one for multiple results (which is a very small price to pay for such a useful utility). Running It You need a very large corpus of email to train a Bayesian classifier like this one. Luckily, the “spamassassin” developers have released a public corpus of email that can be used to develop antispam utilities. (A command-line client for this module is presented at the end of this chapter.) This corpus, broken up into ham and spam of varying stripes, can be downloaded from http://spamassassin.apache.org/publiccorpus/. Running the code on these corpuses gives results not nearly as good as Paul Graham says he got, but they are still very good. When tested on the files that made up the training corpus, the results are quite effective, especially with regard to false positives (nonspam mail was not flagged as spam).

Our function will return a list of triplets containing each word, the probability of seeing that word in a spam message, and the probability of seeing that word in a nonspam message: def word_probabilities(counts, total_spams, total_non_spams, k=0.5): """turn the word_counts into a list of triplets w, p(w | spam) and p(w | ~spam)""" return [(w, (spam + k) / (total_spams + 2 * k), (non_spam + k) / (total_non_spams + 2 * k)) for w, (spam, non_spam) in counts.iteritems()] The last piece is to use these word probabilities (and our Naive Bayes assumptions) to assign probabilities to messages: def spam_probability(word_probs, message): message_words = tokenize(message) log_prob_if_spam = log_prob_if_not_spam = 0.0 # iterate through each word in our vocabulary for word, prob_if_spam, prob_if_not_spam in word_probs: # if *word* appears in the message, # add the log probability of seeing it if word in message_words: log_prob_if_spam += math.log(prob_if_spam) log_prob_if_not_spam += math.log(prob_if_not_spam) # if *word* doesn't appear in the message # add the log probability of _not_ seeing it # which is log(1 - probability of seeing it) else: log_prob_if_spam += math.log(1.0 - prob_if_spam) log_prob_if_not_spam += math.log(1.0 - prob_if_not_spam) prob_if_spam = math.exp(log_prob_if_spam) prob_if_not_spam = math.exp(log_prob_if_not_spam) return prob_if_spam / (prob_if_spam + prob_if_not_spam) We can put this all together into our Naive Bayes Classifier: class NaiveBayesClassifier: def __init__(self, k=0.5): self.k = k self.word_probs = [] def train(self, training_set): # count spam and non-spam messages num_spams = len([is_spam for message, is_spam in training_set if is_spam]) num_non_spams = len(training_set) - num_spams # run training data through our "pipeline" word_counts = count_words(training_set) self.word_probs = word_probabilities(word_counts, num_spams, num_non_spams, self.k) def classify(self, message): return spam_probability(self.word_probs, message) Testing Our Model A good (if somewhat old) data set is the SpamAssassin public corpus. We’ll look at the files prefixed with 20021010. (On Windows, you might need a program like 7-Zip to decompress and extract them.) After extracting the data (to, say, C:\spam) you should have three folders: spam, easy_ham, and hard_ham. Each folder contains many emails, each contained in a single file.

Tinderbox uses a similar system, drawing from your database of notes to produce a bunch of static pages. My book collection pages are done this way. Radio UserLand statically generates the pages on your local computer and then “upstreams” them to your website. Finally, while researching Webmake, the Perl CMS that generates pages like Jmason’s Weblog and SpamAssassin, I found a good bit of terminology for this. Some websites, the documentation explains, are fried up for the user every time. But others are baked once and served up again and again. Why bake your pages instead of frying? Well, as you might guess, it’s healthier, but at the expense of not tasting quite as good.
