Hi Sudhir,

Please try below in your validation rule

NOT(REGEX ( UPPER ( Email_Domain__c ) ,"^[A-Z0-9.-]+@[A-Z0-9.-]+\\.[A-Z]{2,4}$"))

Let me know for any issues.

Have you considered using an e-mail field type? That applies standard e-mail address format validation that will only allow those permitted characters in it:

Thanks for your reply actuall field name is email domain which is a text field.  

I am currently using this belwo valdiation  which is working good will not expect any specical character  
NOT(REGEX(Email_Domain__c, "[a-zA-Z0-9.']+")) && ISCHANGED(Email_Domain__c)

 Now we have a requirement to allow few special character like @ . -  Only these special characters should be allowed. 


 Please suggest me. 


Thanks
Sudhir

Hey Sudhir,

You can try below rule

REGEX ( UPPER ( Email_Domain__c ) ,"^[A-Z0-9._%+-/!#$%&'*=?^_`{|}~]+@[A-Z0-9.-]+\\.[A-Z]{2,4}$")

For more details you refer below link for the same

Thanks Arpit for your reply. for some reason it is not working

Example : When i include ##@gmail.com it is accepting It must accept only if it has - . @ symbols  if any other symbols are enterd it must not accept. 

I Modified little adding ISCHANGED to the code.  
REGEX ( UPPER ( Email_Domain__c ) ,"^[A-Z0-9._%+-/!#$%&'*=?^_`{|}~]+@[A-Z0-9.-]+\\.[A-Z]{2,4}$") && 
ISCHANGED(Email_Domain__c)
 Please suggest to fix this issue. 

Thanks
Sudhir
