I also reached out to them on Twitter but they directed me to this form. I followed up with them on Twitter with what happened in this screenshot but they are now ignoring me.

      Probably, from what I can see the address in question isn’t really that exotic. but an email regex that validates 100% correctly is near impossible. And then you still don’t know if the email address actually exists.

      I’d just take the user at their word and send an email with an activation link to the address that was supplied. If the address is invalid, the mail won’t get delivered. No harm done.

        Actually, one of our customers found out the hard way that there is harm in sending emails to invalid addresses. Too many kickbacks and cloud services think you’re a bot. Prevented the customer from being able to send emails for 24 hours.

        This is the result of them “requiring” an email for customers but entering a fake one if they didn’t want to provide their email, and then trying to send out an email to everyone.

        Our software has an option to disable that requirement but they didn’t want to use it because they wanted their staff to remember to ask for an email address. It was not a great setup but they only had themselves to blame.

          My guess is that would also occur with valid but non-existing e-mail addresses no? The regex would not be a remedy there anyway.

          Of course you should only use the supplied e-mail address for things like mass mailings once it has been verified (i.e. the activation link from within the mail was clicked)

          Personally I don’t think that sucks or is even wrong. Case-independent text processing is more cumbersome. ‘U’ and ‘u’ are two different symbols. And you have to make such rules for every language a part of your processing logic.

          If people can take case-dependence for passwords (or official letters and their school papers), then it’s also fine for email addresses.

          The actual problem is cultural, coming from DOS and Windows where many things are case-independent. It’s an acquired taste.

            Im with the earlier “yeah… No.”

            Because

            “If people can take case-dependence for passwords”

            They cant now do they ? If they could passwords would be a-okay and there wouldn’t be any need for stickies on monitors, password managers, biometrics, SSO, MFA and passwordless authentication.

            The dumbest idea in computing is assuming everyone is as smart as you.

            They aren’t. Why isn’t *nix any bigger? Here’s your answer. People are stupid.

            Why did IT only finally took off with windows 3.11? because people could understand that. Barely. Most of us where way to dumb for everything which came before.

            Why does ipv6 acception takes so long? Because people are stupid and don’t get it. Nobody really gets hex. So they just stay with what they can read and more or less get. Even the hardest part of ip4, subnetting, has an easy way out: just add 255.255.255.0 in there and it works. Doesnt work? Keep replacing 255 with zeros and eventually it will. Subnetting on ipv6? No idea. Let’s just disable ipv6 on the internal lan and leave everything on ipv4. Zero migration, zero risk, zero training needed.

            Why do so many companies only go half assed into cloud? Because they don’t get it.

            Powershell? Only half, a third even, of the admins truly get it.

            I could go on.

            Succes is build on simplicity.

              Oh, I like writing such rants too, so I’ll answer with lots of words.

              They cant now do they ? If they could passwords would be a-okay and there wouldn’t be any need for stickies on monitors, password managers, biometrics, SSO, MFA and passwordless authentication.

              Hardware tokens. With sufficient demand the scale would make them really cheap.

              It’s exactly because of having experience with making work the whole zoo that engineers don’t understand how much easier that would be for normies.

              The dumbest idea in computing is assuming everyone is as smart as you.

              Assuming that everyone is as dumb as me in areas where I’m dumb would also be a mistake.

              Why isn’t *nix any bigger? Here’s your answer. People are stupid.

              Because of oligopoly. People are not stupid, but they have priorities and they don’t have some of the knowledge we have. Also it doesn’t really have to be that big immediately, all in good time.

              Why did IT only finally took off with windows 3.11? because people could understand that. Barely. Most of us where way to dumb for everything which came before.

              Can’t comment on that, I was born in 1996.

              Why does ipv6 acception takes so long? Because people are stupid and don’t get it. Nobody really gets hex. So they just stay with what they can read and more or less get.

No idea. Let’s just disable ipv6 on the internal lan and leave everything on ipv4. Zero migration, zero risk, zero training needed.

              Because not everything supports it right, including some industrial equipment and network hardware, there may be new bugs in everything involved, the old ways work and it’s not just v4 with longer address, so people fear making mistakes in configuration.

              Why do so many companies only go half assed into cloud? Because they don’t get it.

              Now think about similar horrors in, say, piping in houses, or other construction stuff. Or cars. Or roads. Everything is half-assed. It’s normal.

              Powershell? Only half, a third even, of the admins truly get it.

              I kinda get it, but also hate it. Hard to read.

              In general:

              The most precious secret you can get from experience is that people are not stupid when they are given easy opportunity to try many things and choose what they like.

        The best of validation is just to confirm that the email contains a @ and a . and if it does send it an email with a confirmation link.

          TLDs are valid in emails, as are IP V6 addresses, so checking for a . is technically not correct. For example a@b and a@[IPv6:2001:db8::1] are both valid email addresses.

            I feel like using a@[IPv6:2001:db8::1] is asking for trouble everywhere online.

            But its tempting to try out, not many people would expect this.

    The best way to validate an email address is to sent it an email validation link.

    Anything outside of that is a waste of effort.

    That is 100% a bot, and whoever made the bot just stuck in a custom regex to match “user@sld.tld” instead of using a standardized domain validation lib that actually handles cases like yours correctly.

    Edit: the bots are redirecting you to bots are redirecting you to bots. This is not a bug. This is by design.

    My Ameriprise account has its own email address because the fuckers don’t believe any email starting with email@ is a real email. I’ve called them a million times and got them to file a bug, which they did, and then closed as won’t fix.

    No, dots are NOT necessary. Actually you do not even need to supply a domain or a top level domain because mails then default to the default system which is usually localhost.

    But even for routed mail there doesn’t need to be a dot.

    There is still valid Bang-Adressing for UUCP routed emails:

    !bigsite!foovax!barbox!me

    This is a valid email which basically means “send my email to bigsite, from there to foovax, then to barbox, to the user me.”

    And if you are in a playful mood - mix FQDN and BANG addressing…

    A couple of years ago I made Hotmail crash by sending a mail to googlemail.de!hotmail.com!googlemail.com!hotmail.de!googlemail.ca!hotmail.ca!googlemail.fr!hotmail.fr!.. [repeated it for 32kByte] …!myuseraccount - their server literally crashed completely all over the world for like 15 minutes. I am so proud of myself but then it was their fault for not complying to RfC822.

        I’m assuming by “dot” you meant @

        In fact both are optional. With FQDN-Adressing a user without domain defaults to localhost, with Bang-Adressing there is no @ because the last system is left for interpretation of the last receiver and if he consideres it a user, so be it.

        Right? Always make personal accounts tied to completely independent email accounts. Never ISP, work, or school email accounts. It makes it hell to deal with if you want to switch providers, quit or get fired, or graduate. It’ll take weeks to get into all your old shit.

          It’s my spam email I use for accounts that aren’t important. And I graduated a long time ago, it’s my email forever.
