Thanks! 1. Can you send an email to iou@iou.ch so I can check you address and fix the bug? 2. We will be building mobile apps as soon as possible with this fun

  Please read up on present day email address validation. If you have a regex that is doing more than ^.+@.+$, then you are doing it wrong. Don't validate the address beyond looking for an '@' in the string; just send an email with a confirmation link to see if it actually works.

    Thanks we will change this!

    100% this! For reference, I didn't try any of the more obscure email address features, such as comments or quotation. My address simply has the form firstname@lastname.email

    I use: ^[^@]+@[^.]+\..+$ for a bit of sanity checking...
    • dalbotex 7y ago
      Multiple @ symbols are absolutely valid, as long as they are properly quoted ;)

    > just send an email with a confirmation link to see if it actually works. Please don't enable anyone to just send emails to arbitrary email-addresses through you. That's how your email/domain will quickly get marked for SPAM. At the very least, put in place a rate-limit per email-id (and source-ip too maybe). Otherwise i can simply keep entering email-ids of people to spam.

      Why the -1's ? Isn't this a genuine concern to avoid getting on a SPAM blacklist? What am i missing?...

    I prefer the true email validation regex: https://regex101.com/r/iE0rF5/1 https://regex101.com/r/iE0rF5/1

      I feel bad for the developers who run into that monstrosity and actually implement it.
