Validating email address in c
If it all works, you can continously monitor your address list to ensure email addresses continue to be valid - Some mail servers may return a positive response even if the mailbox doesn’t exist.

I know that I have to search for the @ symbol.I don't know how to make sure that it is before the dot..make sure there is text before it..text after the dot..help would be appreciated! That said, you can try checking the criteria manually, one step at a time. They turn in your program, get a grade, and move on to more difficult concepts they still don't understand because someone always just gave them all the answers.
First check to see if the first character is alphabetical. Second, check to see if there is only one @ in the address. Third, check to see if the character after the @ is not a dot. It's tantamount to, say I come with a question on how to calculate the derivative of x Er, what is this for?

As it is, the code so far doesn't even come close to properly validating an email address.The problem is so complex, actually, that the complete, industry-standard, regex for it is actually broken.(By the way, here it is: The standard itself: if this is a homework, your teacher will have to have given you some constraints he expects you to use, since an email address is such a warped and twisted thing that whatever you code, someone, somewhere will have a valid email address that will not validate with your code.Mail Address class to check if an exception occurs when creating the e-mail to determine if it is a valid or not : I suppose it depends on how you are currently sending it, but you might consider checking out this related Stack Overflow discussion along with this one which covers a few different techniques to try and check if your message was sent ().
Another important point to consider is that do you need to be performing this?Using OWASP Validation Regex The idea is simple; we will use OWASP Validation Regex repository.
