Email id used while filling up exam form

Hii

I have filled up ca final exam form using an email ID which i dont use for my official purposes. the Email ID contains ca_myname @ red******l.com

I opened this email ID ahead of time as when i become ca it may not be available.

Now, I do not know if it is violation of any rule as such but I am worried whether my exam form will be rejected due to using this email ID while filling up the form. I submitted my form today.

Kindly throw light. I m worried.
