Sorry, this is not a correct regex for an email address.
Sending using
mailon a local unix system? You only need the local part.STOP VALIDATING NAMES AND EMAIL ADDRESSES. Send a verification email. Full stop. Don’t do anything else. You really want to do this anyway, because it’s a defense against bots.
*Gasp* the registration is coming from inside the colo!
I think it’s fair to prevent users from causing mail sent to your internal systems. It probably won’t cause any issues getting mail to the machine inbox for (no domain name), but it reasonably makes security uneasy.
The statement I was responding to was “This is the correct email regex”. There is no correct email regex. Don’t parse emails with a regex. You probably don’t need to parse emails at all.
Yes, but no. Pretty much every application that accepts an email address on a form is going to turn around and make an API call to send that email. Guess what that API is going to do when you send it a string for a recipient address without an @ sign? It’s going to refuse it with an error.
Therefore the correct amount of validation is that which satisfies whatever format the underlying API requires.
For example, AWS SES requires addresses in the form UserName@[SubDomain.]Domain.TopLevelDomain along with other caveats. If the application is using SES to send emails, I’m not going to allow an input that doesn’t meet those requirements.
You mean the validation which the underlying API will perform on its own? You don’t need to do it.
