So, she asked me what the email address for ICICI Bank's customer care was. A google search threw up the answer and I told her. A little while back she came back and said it was asking her to check the address she was using. I re-checked the email address she was using. It seemed to be correct. I asked her whether she had logged into her Rediffmail account. She asked why she needed to do that? I was a little horrified.
I asked her where she was typing the email address I gave her? She said in the line where she types addresses. I quickly figured out that she was typing the email address in the browser URL field!
I then explained to her that she needed to log in to her Rediffmail account to send email!
