I think the spammers need some help with their regular expressions….  

1. See http://github.com/palepurple/policyd-weight – I’m trying to make some changes to policyd-weight (something I’ve been using for ages) to make it more configurable and add in a GeoIP patch which I’ve seen floating around. 2. See https://twitter.com/excommunicado and http://blog.hinterlands.org/2013/11/an-update-on-communicado/ – for a DNS Blacklist you might want to use –  using excommunicado.co.uk as a RHSBL has stopped about 700… Continue reading spam (policyd-weight + excommunicado)

And a new theme. Perhaps one day I’ll fix my twitter sync script. In the mean time, there’s a bit on Solr on Pale Purple’s blog. along with SpamDyke to stop Qmail being overrun by spam.

Recently on the Twitter the following (attached) image came up – presumably legit, of a job advert. Highlights below. It’s almost like someone cut and pasted two job postings together. The phone number does appear to be legit … so perhaps the advert itself is?

One of my customers uses Akismet to protect his various blogs from the masses of spam.

NFS really can be a major PITA. Our office network has been breaking all day. This seemed to coincide with moving more of our computers to gigabit ethernet (removing the 100mbit CISCO 7960 phones which their network had been daisy-chained through – and seemed to cause intermittent packet loss) Here are some tips for others… Continue reading Stupid NFS (Debian Squeeze / Ubuntu Precise)

At work we keep receiving emails from sales-droids in India who are trying to persuade us to outsource PHP/Android/Java/whatever development to them. Here’s my first attempt at a spamassassin rule to neutralise it – in my case, copy into a something.cf file in /etc/spamassassin/mail, and running over a suitably loaded email results in : Content… Continue reading SpamAssassin ruleset to try and catch India based web development spam

Scenario – one Linux box runs multiple Postfix instances. By default they all log to /var/log/mail.log which makes it difficult to see what’s going on without using grep and so on. The server already uses rsyslog, and Postfix is configured to specify a syslog_name to each instance. i.e /etc/postfix-blah/main.cf contains “syslog_name = postfix-blah” rsyslog allows… Continue reading rsyslog selective logging with multiple postfix instances

I keep forgetting these one line OpenSSL commands – perhaps if they are here, I’ll remember — Create private key file : openssl genrsa -out server.key 2048 Create certificate signing request (to send to e.g. GoDaddy) – openssl req -new -key server.key -out server.csr  Verify a certificate – openssl verify file.name To convert a .crt… Continue reading SSL Commands
