I have email accounts on all the major email sites including rediffmail(which is my oldest) and also on yahoo etc. Rediff unfortunately is the worst because I have to deal with many of my clients via email and rediffmail has cost me around 30000 rs believe it or not.I would like you to take this very seriously so that you dont lose your money and clients like I did and only use gmail for interaction of any kind specially if its for official purpose.
It is easy, fast, secure and has all the features and most of all , all the emails are delivered unlike in rediffmail and sometimes even in yhaoo, hotmail , etc
