A useful mail from my mail box for you:-
I have faced one problem while registering DSC for Income Tax Efiling, It has given following error :
"The Certificate doesnt contain your email address."
The error was due to different email used in DSC and Income Tax record.
Email in DSC and Income Tax Efiling record has to be same if we want to use DSC for Income Tax Efiling.
Where you will find your email in DSC?
1. Go to Tools - Internet Options - Content - Certificates.
2. Select Certificate & Double Click on that certificate.
3. Click on "Details" tab.
4. In Details, Click on "Subject" (In case of Ncode DSC Click on "Subject Alternative Name"
5. Here you can find ur Email.
