Mistake in RNAME

DNS admin always mistake in RNAME field of SOA records.

for example:
suppose my email address is dikshie.fauzie@gmail.com

this is wrong:
dikshie.fauzie.gmail.com , it becomes dikshie@fauzie.gmail.com 

this is correct:
dikshie\.fauzie.gmail.com, it becomes dikshie.fauzie@gmail.com
