Hi @Aypn CNN ,

email id name should contains one dot (.) and email id name starts with alphabets only, length would be minimum 5 chars and it is end with preferred domain names, all small letters,

According to your description, I have two questions of your descriptions.

1. what's the preferred domain names?
2. which words' length are minimum 5 chars? Before @?

Now, I have do a test to meet 3 requirements.
1.contains one dot (.)

([a-z0-9_.])+\.  

2.starts with alphabets only

[a-z]  

3.all small letters

 [a-z]  

The complete regex with the 3 requirements:

/^(([a-z])+([a-z0-9_.])+\.)+([a-z])+\@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9])+$/  

Best regards,
Yijing Sun
