Control of maxlength for email field

  • I want to control the input string length of the email field, to prevent spammming when email2 is sent back as a reply to the form originator. I have set the maxlength for the email field, which limits the characters in the form.
    However, a lot of spam is bot generated, so will the maxlength validation work if a bot autofills the form? I have other measures in place to minimise bots, really just wondering how this parameter works. Thanks.

    Thanks for the reply.
    The page you referred to I know about, but it does not answer my question.

    The maxlength limits the characters in the form field, BUT what if the form is completed by a bot automatically, and not by a human. Can such a process bypass the maxlength validation? Id the maxlength validation done by javascript locally or server side?

    The reason why this is important is to make sure we have a good way to prevent the email field being filled with multiple (sometimes thousdands) of email addresses, which are then spammed with the mail2 responder, instead of an email just going to the form originator.

    No.

    Done on server side.

    Thanks for confirming, much appreciated. This will definitely add a much needed level of hindrance to spammers.
