If you are webmaster and managing your server, you probably remember that sad day when you learn;
As of December 6, 2012, Google no longer offers new accounts for the free edition of Google Apps. Google Apps free edition is sometimes referred to as “Standard Edition.”
It was just sad. I was happy to provide google mail system to my clients. I dont want to host mails in my own server so i needed an alternative to Google Apps Standard Edition and i realize Yandex started to give an alternative feature to Google Apps!
I tried and i liked it :)
I couldnt find english version of this feature, probably they are preparing it for worldwide. Check http://webmaster.yandex.com/, maybe its already released while you reading this :)
