We received too many requests for the beta testing phase of our Anti-Spam Mail Gateway service. We apologize we could not accept them all due to limited slots available. However, for all the people who are curious about how the stuff works, we are adding in an image for reference. One of our beta tester client is a nice and friendly 56 years old lady blogger. She is a granny of 3 small cute kids and she blogs about her life with them for fun. However, the spam traffic on her primary domain was quite bad. She asked her for help as she was receiving more than 6000 spam mails in a day and had tried many different anti-spam solutions which did not help her much.

We put her domain on our mail gateways to scan the mails for her and the results she got exceeded her expectations. Within 24 hours, we blocked around 6500 spam mails for her and also 19 Virus mails. Around 380 mails were legitimate and passed along to her mailbox. Here is the graph for reference.

Our mail gateway services are now live. You can contact us for any queries you have about the service or for bulk pricing options. We have limited number of slots available still for shared gateway services, however, we can certainly deploy dedicated anti-spam gateways within a few hours as we have now developed a fully tested setup and configuration for the mail gateways. We appreciate your questions and feedback as always.

Amavisd-new is a high-performance and reliable interface between mailer (MTA) and one or more content checkers: virus scanners, and/or Mail::SpamAssassin Perl module. It is written in Perl, ensuring high reliability, portability and maintainability. It talks to MTA via (E)SMTP or LMTP protocols, or by using helper programs. No timing gaps exist in the design, which could cause a mail loss. Amavisd-new is a basically an interface which uses a “scan and pass” method for both inbound and outbound mails. This functionality is very similar to Google’s Postini Mail scanning services or the Barracuda Spam Firewall services. While other such services require a good amount of financial investment, amavisd-new can run off a normal Linux machine and is open-source.

We are now providing both dedicated anti-spam gateway servers and shared anti-spam gateway services as part of our custom solutions services. The dedicated anti-spam mail gateway servers can scan both your inbound and outbound mails for spam content,viruses and phishing content. They minimize the impact of spam  mails on your business and discard most junk. The dedicated anti-spam mail gateways are fully managed along with any custom configurations that needs to be done to your current mail servers as well. We currently have prebuilt tailor made gateways available to work with Cpanel servers. All mail servers and control panels are supported on these gateways but for any control panel or setup other than cpanel, the gateways need to be custom built. Amavisd-new uses spamassassin and Clamav Antivirus on these Cpanel mail gateway servers to scan the mails.

We are also offering shared anti-spam gateway services currently. These services are specifically for businesses who have moderate mail activity and cannot afford dedicated anti-spam servers. This service is currently in beta testing phaze and you can email us at betatesting at rrdns.com to get a shared anti-spam gateway account with us. Please note that currently only cpanel servers are supported for the shared anti-spam  gateway services and you would need a cpanel based dedicated server or VPS to be able to use this service.

Please feel free to contact us for any queries about the anti-spam mail gateway service.

1. Anti-Spam Mail Gateway Live Statistics Hello People, We received too many requests for the beta...

We have been testing out a new product recently which has been specifically designed for load balanced setups on shared hosting servers. We deployed this product for testing purposes across some known good shared hosting service providers. Dreamhost.com has been one of them and so we are sharing our thoughts about their services.

Setup:

The setup was almost instant and we got the mail with the login details within minutes. We had signed up for their 30 day free trial first. We really liked their uptime and security setups on the servers and so went ahead and paid them for the rest of the term of the plan.

Control Panel:

Dreamhost runs their own perl based proprietary control panel. It is customized to provide all the offerings they can provide on the shared servers as well as custom setups like Google MX or Jabber IMs are available in it as well. The control panel may need some hosting knowledge before hand as some options available in are quite geeky. Overall, its fast and does it works. We could not find a single option which was buggy or did not work in the control panel.

Some of the features we really liked in their control panel are as below:

1. Amazon Cloudfront Support

2. Subversion Support

3. Media Streaming Support

4. Jabber IM Support.

5. 50G of backup space.

6. Ability to create Unix groups.

If you are someone who loves to work with SSH access, dreamhost is the host for you as you can host unlimited domains with them in a single account.

Server Performance:

The best part we liked about their hosting services was the server’s performance. We did not see a single minute of downtime since we used them ( Yes!. We have been monitoring using a third party service which checks the sites each minute ) and the sites are quite fast. With 15-20k unique visitors a month, we have not had even a single report of someone sending us a note that they cannot access the site. The network connectivity just seems top notch.

Overall Results:

We really did like their hosting features a lot. Overall we would rate them 4.3 on a scale of 5. The only thing they appear to loose out on a not so user friendly control panel although their wiki has every bit of information you need. However, you require some skill to setup things like mail piping etc. with their servers. We actually cannot give out much details on the exact project we tested their services but we can surely say that with the amount of traffic we had been generating, it was a tough stress test for their servers in which they performed very well.

You can get a $5 discount when signing up with them for an unlimited disk usage and bandwidth yearly plan by using the coupon code as “rrdns5bucksoff” currently. Happy Dreamhosting

We have had an enormous response to our services ever since we have launched them commercially. We appreciate all your queries and we will always try our level best to satisfy them all. We have noticed a common trend with most of the clients from whom we received information or quote requests. They asked us for example sites where in the round robin DNS has been implemented for them to review the speed, functionality and benefits of these services. We have now setup a demo site ourselves which shows the entire range of features we can offer with this service. The demo site’s URL is http://www.downlods.info and we will be explain more about the unique setup step by step below:

1. The domain hosts a wordpress site which has almost 1700+ random articles from different RSS feeds found on the web. We are still populating the site with more and more content and we intend to put in a few thousand pages/posts on it so that we can show how a resource intensive can work on the clusters. The first thing you should notice is that the site uses round robin DNS and so it has two A records.

[root@server ~]# host downlods.info
downlods.info has address 69.10.60.149
downlods.info has address 69.10.48.100

Thus the domain runs from two different IPs to balance out the traffic on the domain using round robin DNS configuration.

2. These two IPs run lighttpd installations with PHP configured on FastCGI mode. This can be seen as below:

[root@server ~]# HEAD 69.10.60.149
200 OK
Connection: close
Date: Thu, 24 Dec 2009 09:29:42 GMT
Server: lighttpd/1.4.23
Content-Type: text/html

Client-Peer: 69.10.60.149:80

[root@server ~]# HEAD 69.10.48.100
200 OK
Connection: close
Date: Thu, 24 Dec 2009 09:29:46 GMT
Server: lighttpd/1.4.23

Client-Peer: 69.10.48.100:80
Client-Response-Num: 1
X-Powered-By: PHP/5.2.10

Lighttpd has been custom tweaked on these servers to handle scripts like wordpress and acts as a proxy to pass http requests to much lighter Nginx instances. You can notice the actual site is served from Nginx as below :

[root@server ~]# HEAD http://www.downlods.info
200 OK
Connection: close
Date: Thu, 24 Dec 2009 09:28:25 GMT

PHP is configured to run in FastCGI mode across the clustered setup and thus gives amazing speed to the blog site. You can use various third party tools to confirm the site speed even when the blog has more than 1700 posts and runs numerous ads as well. Here are some of the readily available tests we have already done.

The various results can be found at the links below:

The domains we host on our shared clustered servers as well as on our custom built dedicated clustered have similar configuration and speed like this test domain. They infact have higher performance as each cluster is deployed with tweaks needed from a pre-hosting professional analysis of the sites we do. If you have further questions with the site setups on clusters, please feel free to contact us for clarification.
