Spam Prevention

What is Spam?

Spam is an annoyance for most email users.

When FRII talks about spam (in the context of email), we’re referring to emails that are both unsolicited and bulk. For your convenience, here is a more technical definition from Spamhaus.org, a reputable anti-spam protection organization:

An electronic message is “spam” if (A) the recipient’s personal identity and context are irrelevant because the message is equally applicable to many other potential recipients; AND (B) the recipient has not verifiably granted deliberate, explicit, and still-revocable permission for it to be sent.

How to use mailing lists

Types of Mailing Lists

MailingList

Mailing lists are a convenient and adaptable method for email users to manage electronic mail distributions. These lists are typically used, and are subsequently named, for one of two purposes: announcement and discussion lists. Announcement lists are used to distribute email to a group of email addresses for newsletters, periodicals, and marketing materials. Discussion lists are used to provide a forum for individuals to participate in moderated or un-moderated discussions on topics of particular interest to them.

Bulk mailings should be done using email mailing lists.

If you need to send an email to a lot of people all at once, the best way to do this is through an e-mail mailing list. Most email providers won’t allow you to send too many emails without one (for instance, FRII has a rate limit that doesn’t allow any user to send email to more than 150 recipients in any five-minute period. Here’s a link to current rate limits for some major providers). Continue reading

Bottle.py to Apache mod_wsgi

logos for Python, Bottle, and Apache

Recently I have been building some small Python-based web tools for internal usage here at the office. I decided to use Bottle for handling the request routing, etc. I happen to like microframeworks for small projects such as these. What I’m going to post here today is some of the structure I built around Bottle to integrate it with Apache httpd (mod_wsgi), and allow more easily for multiple code files.

Can we really trust the cloud? – Service Availability

It’s a question I hear discussed a lot (yes, the people I hang out with are so geeky that this is how we pass our time) – Can we trust the cloud? It’s not an unreasonable question, but people have a hard time coming to a consensus. In part, this is because they come at the question from different directions. Some people start talking about service availability. Others start talking about data security. Both aspects are worth looking at. Today we’re going to look at service availability.

Email Clients – What is POP3?

POP3 and IMAP4 are the two vastly most popular protocols for a computer to interact with email from a mail server. As a NOC Technician, one of the most common questions I run into on a day to day basis can be summarized as, “What the heck are those?” This is a question I hope to answer in this post, at least for POP3. I’ll be covering IMAP at a later date.
