  • 0

I have a RegEx for validating email addresses, but I’m really looking to validate a whole From header. Any of these would be valid:

name@domain.com
<name@domain.com>
My Name <name@domain.com>

Is there anything out there that would validate these as valid from headers? I’m going to look in the smtp library 🙂

    I couldn’t get the posted response to work, so I’ve been working on this and finally got this one, which seems to work so far. I’m sure it’ll miss/catch something, but it’s working for now.

    [a-zA-Z0-9+_\-\.\ ]*[ ]*<?[a-zA-Z0-9+_\-\.]+@[0-9a-zA-Z][.-0-9a-zA-Z]*.[a-zA-Z]+>?
