Email Checker – Free online tool for verifying an email address

Do you often send email to new people and sometimes you’re not sure whether that mailbox actually exists or not ? Then you should use some email verification tool, it will help you avoid wasting time on dealing with invalid email addresses.

Check out : http://email-checker.net

email checkerIt started out as a fun side project just like my other weekend projects (like this port checker tool and another one on creating signatures) but now I’m thinking to add some more features in next release and also launch an API for bulk email verification stuff and so on. (based on some recent feedbacks from the users)

How does it work ?

It involves four simple steps :

  • First, the regex check where it simply checks the syntax of the email (something@validdomain format).
  • Next comes the domain validation. If the domain is invalid (doesn’t exist) then there is no point in going any further.
  • Third step involves extracting MX records from the DNS query result.
  • In final step, it connects to the SMTP server and tries to simulate sending a message. Most of the servers (e.g gmail) responds with appropriate response depending on whether the mailbox exists or not.

Example : When user enters a non-existent email address name@example.com, the response is :

No mail server for name@example.com

how to install thunderbird on ubuntu 11.04/11.10

Mozilla Thunderbird is the most popular open source email / news-feed client. It is free and available for all operating systems such as Windows, Mac OS X (Leopard, Lion..) and Linux based OS such as Ubuntu 10.10, 11.04, 11.10. Ubuntu (upto the version 11.04) ships with Evolution Mail client, although it has a lot of features but Thunderbird is much simple and easy to use; from the next Ubuntu release (Ubuntu 11.10 – code named as Oneiric Ocelot), Thunderbird may be the default mail client.thunderbird-logo

Thunderbird is one of the popular software from the Mozilla Foundation. It is popular because it’s very simple to use, and it has a lot of features with great user interface. The most important feature is that you can customize it as you want, extend it as you want because a lot free plugins are available on the web. It has built-in RSS/Atom reader, so it can be easily used as a news aggregator. Here is a snapshot of Thunderbird, running on my Ubuntu Desktop – with a Mac OS X theme.
