Spam – Filters and Eventual Prosecution
A spam kingpin was recently sentenced heavily for his actions. This is excellent. Everyone hates spam. Most people have some sort of spam filter to deal with it. I myself have dealt with is to the maximum, which I have discussed to a great extent in previous posts. Here is a good post about sendmail and how it integrates with spamassassin:

Ultimately you can practically eliminate spam but further introducing blackhole lists to sendmail:

Some progress has been made on the other end of the spectrum.
One of the most notorious U.S.-based spammers was sentenced to more than four years in jail on Monday for a scheme that used spam to manipulate stock prices in order to make a profit.[Source]

I am in the initial states of controlling the processes, but the algorithms are complete to read if the processes are running. Currently the app scans for Apache, Mysql, [...]

Image via Wikipedia The core of Linux is designed to mail, at minimum, the root user of various system alerts. With sendmail installed these alerts are mailed to the respective user directory.

To stop the emails from coming add this to the end of any particular cronjob: >/dev/null 2>&1 Without the above line the email will be delivered to the [...]

I tried for a long time to get sieve to work with sendmail. I could not get it to work. I would try and create a custom .m4 mailer, as per the sieve pages on the dovecot website, but nothing would work. Ultimately I gave up and used client side mail filtering built into Thunderbird. [...]

Maybe someone will help me. A rare thing to ask, but I cannot get sieve to work on my server. The plugin page, on the dovecot website, appears rather simple. http://wiki.dovecot.org/LDA/Sieve Install dovecot, then activate the sieve plugin. Here is what happens. I setup sendmail to use dovecot’s deliver and mail is no longer being [...]

I’ve gone over sendmail several times, but ultimately it comes down to a couple of factors. Unless you are setting up an enterprise level email server, and require some login settings, and potential relaying, sendmail is relatively simple. You start by installing it: sudo apt-get install sendmail Sendmail operates on port 25 because it is [...]

Ive had a mail server for a long time. Ive always used the built in Spamassasin that Thunderbird uses. I recently got a blackberry and was receiving the spam even though Thunderbird was successfully filtering the spam to the Junk folder. This is because the MTA, Dovecot in my instance, was transferring the mail to [...]
