The staff here at Purity Networks has been working hard on some new features and functionality that we’ll be rolling out over the next few months. I wanted to take a few minutes and tell you about some of the things that are coming and approximate timeframes on when you’ll see them roll out:

New Integrated Live Quarantine

We will soon be integrating the Live Quarantine system into the Account Manager.  This will allow us to integrate the logins into one site, rather than having two separate sites as there are now.  One of the advantages of this is that the ability to theme the Account Manager is much more robust than the current Live Quarantine system.
Planned Release: February 2010

Additional Admin Accounts and Fine-grained Access Control

When the Live Quarantine is combined into the Account Manager, one of the major advantages is that we will also be rolling out the ability for our customers to give accounts access to administrative functions.  This access control will be very flexible and will allow the customer to give access to various areas of the Account Manager and even restrict access to specific domains.
Planned Release: February 2010

New Backend Technology

We will soon be replacing the backend scanning technology that we use with a completely new system.  The new technology we’ll be using is the same technology that will be going into our forthcoming antispam appliances.  Many of you know that we currently use technology from MailFoundry as our scanning engine.  We’ve used their products as the core of our service since we launched in 2005, and were extremely happy with their technology until recently.  Unfortunately, we feel that they have not been keeping up with changes necessary to effectively combat spam and other threats.

The core scanning technology we’ll be using in our new backend services and in our appliances is from Cloudmark, and we’ve been testing its effectiveness for several months now.   We’re happy to report we are extremely pleased with the performance and effectiveness and are beginning integration work now.
Planned Release: April 2010

We have some more things planned for this year as well, but I’ll leave those for a later message.  I think the things I posted above are enough to keep us busy for a little bit!

Please let us know if you have any questions or thoughts about our forthcoming changes.

This morning at approximately 7am central time, our MF2 gateway began to experience issues. Although the gateway was up and responding to network requests, it was not responding to SMTP requests. After investigating the issue it appears that the gateway was hit with an extremely heavy dictionary attack, essentially to the point of a denial of service, sent to a domain that was misconfigured and was not rejecting unknown users.

This caused our gateway to accept all mail received for that domain and queue it up in an attempt to deliver it to the destination server. Due to the large volume of mail, it caused the gateway’s processor load to spike, causing the gateway to shut down SMTP services to protect itself.

Once we determined what the issue was, it took us some time to go through the outgoing queue and remove the offending messages from the queue manually to reduce the amount of work the gateway had to do so that processor levels could be reduced enough to enable SMTP again.

SMTP services were re-enabled at approximately 8:30am central time and all mail should be flowing normally. No mail will have been lost during this outage, though some mail may be delayed past the point where services were restored due to the retry settings on the sender’s mail server.

We apologize for this outage and will be discussing internally ways to prevent something like this from happening again. The most likely outcome of this will be that we will fully activate the automated catch-all checking and disabling, which is designed to disable domains that accept mail for all users like this. We’ve put off doing so several times in the past due to customers expressing concern about it, but I believe it’s time to go ahead and implement this for the sake of all of our users.

All customers with service on MF2 will be receiving a 5% service credit due to this outage.

Thank you all for making 2009 such a great year for us! We’re looking forward to continuing to help you keep your mailboxes clean in 2010.

In the next couple of weeks we’ll be releasing the new API version 2.0, which will make integrating Purity Networks services with your infrastructure much easier. Keep an eye out over the next couple of months for some really exciting integration news as well!

Over the next 6 months we’ll be launching some great new services, upgrading our filtering technology significantly and expanding our infrastructure as well. We’ll keep you all in the loop here on the blog, but be sure to let us know if you have any ideas for new features or services you’d like to see from us!

We wish you all a Happy New Year and hope that it brings you much joy and prosperity!

I want to take a quick moment and wish everyone a Merry Christmas and Happy Holidays from Purity Networks!  We thank you for your business and look forward to reducing the junk in your email for another great year in 2010.

Once again, thank you for your business and Merry Christmas and Happy Holidays!

Just a quick note to let everyone know that we’ve made some visual changes to the ReportCenter functionality of our Account Manager, making the graphs quite a bit easier to decipher as well as better color coding.

Over the next few weeks you’ll see some more changes, most notably behind the scenes with the report data itself.  We’re working on expanding the data that we capture and have available for reporting as well as fixing some issues with the data that we’re gathering currently.  We’ll likely also be adding some additional graphs and reports to the ReportCenter.

Have ideas for data you’d like to see, or different ways to present data?  Comment on this post or email us at support@purity.net so that we can take the ideas and suggestions into account as we build out new reporting features.

With the release of UserProtect, we’re working on a new version of the Purity Networks API to incorporate functionality to work with UserProtect and DomainProtect accounts.  We’re still in the early design and development stage, but we’ve started working on the documentation on the Wiki at the same time to give our users input into the design.

Please see the new wiki section to take a look at what we’re working on.  The new version of the API is not going to be a SOAP API like version 1.0 is.  It’s going to be a RESTful API, which is much easier to work with.

Please give us as much feedback as you can so that we can take it into account as we develop the new version of the API.  Have thoughts or comments?  Let us know in the comment section below or in the discussion section on the wiki page.
