How to: Find out domain expiration date

My friend recently lost her domain name as she forgot to renew it. Now there is no way she can get back the domain name. So how do you find out domain expiration date?

There are 3 simple ways:

By checking the public WHOIS database

Visit whois service here and enter your domain name. You can also use your domain registrar whois service to find out information.

By logging into your domain service providers account

Login to your domain registrar account and list expiring domain. Make sure you set all domains to auto renewal. Finally, make sure your credit card / payment information is upto date to avoid delays.

By using automated shell scripts for Linux /UNIX / Mac OS X

You can grab modified shell script that run as a cron job from your own Mac OS X / Unix computer. This script checks to see if a domain has expired. It can be run in interactive and batch mode, and provides facilities to alarm (email) if a domain is about to expire in advance.

Free Windows Software

If anyone has any information about free domain remainder utility for Windows XP / Vista, please add them in the comments.

Most domain register provides a series of reminder emails to you as the domain name approaches its expiry date. Make sure you whitelist those email address. If domain names are quite important register them for 5-10 years and lock all domain names.

Free POP3 server for personal use

My friend recently asked me a question:

Where can you find a free POP3 server?

POP3 has made earlier versions of the protocol obsolete. Generally you will not find a free POP3 server. Usually your ISP or webhosting company provides IMAP or POP3 access.

But where can get a free POP server?

You can use Google’s GMAIL service which provides a free POP3 service. You can download email using POP3 and send email using Googles SMTP server. According to Google:

POP, or Post Office Protocol, lets you download messages from Gmail’s servers onto your computer so you can access your mail with a program like Microsoft Outlook Express or Netscape Mail, even when you aren’t connected to the Internet.

POP access is free for all Gmail users and we have no plans to charge for it in the future.

20 most wanted Firefox extensions

There is a good list of 20 must-have Firefox extensions published at computer world web site. These plug-ins give you souped-up functionality, better look and feel, and streamlined development tasks.

Currently I am using following two add-ons
1) Google Toolbar
2) Stumble! Toolbar

You can find some other Firefox add-on information here :)

A freshly installed copy of Firefox is a great software package, but what makes this open-source browser so special is the ability to customize it via extensions and themes to really make it yours. The problem is, there are so many available add-ins, it’s tough to know what’s worth installing and what’s just going to junk up your system.
