Hi,
I have a requirement to write a shell script to judge/identify the records whether the email is good or bad. Below is the pre-requisites client has given
Valid domains for email address acceptable as "COM,EDU,NET,ORG,INT,GOV,MIL,AERO,BIZ,COOP,INFO,MUSEUM,NAME,PRO"
and also need to check the below conditions
a) 'Characters ()<>,;:\/"''[] or spaces are not permitted in an email address.';
b) 'An email address cannot contain control characters or DEL.';
c) 'An email address cannot begin with the dot or at-symbol.';
d) 'Names like root, webmaster etc. are unacceptable.';
e) 'An email address cannot have a dot immediately after the at-symbol . ';
e.g :- A file contains data as below
