["validate-email","Please enter a valid email address. For example johndoe@domain.com.",function(e){return Validation.get("IsEmpty").test(e)||/^([a-z0-9,!\#\$%&'\*\+\/=\?\^_`\{\|\}~-]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z0-9,!\#\$%&'\*\+\/=\?\^_`\{\|\}~-]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*@([a-z0-9-]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+(\.([a-z0-9-]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF])+)*\.(([a-z]|[\u00A0-\uD7FF\uF900-\uFDCF\uFDF0-\uFFEF]){2,})$/i.test(e)}]

The type of email in which backlash is there e.g. john/smith@domain.com, john#smith#@domain.com or john*smoth@domain.com are not showing error for validation of emails.

What I can do to fix?

Create a new javascript file and place it in /js folder.

For example : js/validation-override.js

Validation.add("validate-email","Please enter a valid email address. For example john_smith@domain.com.",function(e){return Validation.get("IsEmpty").test(e)||/^([\w-\.]+)@(([[0-9]‌​{1,3}\.[0-9]{1,3}\.[‌​0-9]{1,3}\.)|(([\w-]‌​+\.)+))([a-zA-Z]{2,4‌​}|[0-9]{1,3})(]?‌​)$/i.test(e)})

Add this code inside your theme layout xml file app/design/frontend/your_theme/default/layout/page.xml :

<default>
    <reference name="head">
        <action method="addJs"><script>validation-override.js</script></action>
    </reference>
</default>

  • Doesn't work john/smith@domain.com, john#smith#@domain.com still validating.. – Shoeb Mirza Feb 8 '17 at 17:57
  • Are you sure your overriden JS file is loaded? Maybe browser cache? – Jonathan Ribas Feb 8 '17 at 19:08
  • Yeah, your code is working but it doesn't achieve what I wanted. I just don't understand how to avoid special characters in the names except "fullstop" and "underscore" – Shoeb Mirza Feb 8 '17 at 19:17
  • For what you want to achieve you have to change the regular expression in js/validation-override.js – Jonathan Ribas Feb 9 '17 at 10:09
  • Let's say I don't want to allow John/Smit@domain.com type or John*Smith@domain, how can I achieve this by changing regular expression? – Shoeb Mirza Feb 9 '17 at 19:47
