I need to store in a Table messages which are sent using a classical web page CONTACT US.

My question is:
Would be better doing email validation on Business layer or better at Data Base level?

Regarding email validation in BL I would like to know if using asp.net 4 there is some sort of automatic system for validating emails instead of complicated regex or similar.

Regarding validation in DataBase I found out this article, seems quite useful.

I would appreciate your opinions.

Thanks for your support 🙂

    I would handle the validation at the business layer. I try to keep as much logic out of the database as possible.

    Also, I don’t worry about getting the perfect regex for email addresses. I usually just check that it contains an @ character. I don’t want my validation to disallow some valid email address that I didn’t think of. If I want to be sure that it’s a good address, I’ll send an email to it, and ask them to click a link to validate their email address.
