    I’m trying to email form data from a web page to my 1and1 email account but it is rejected for authentication reasons. Can I use Pear or PHPMailer with Windows Hosting to send the email with authentication?

    I have been trying to do this but it does not work.

      Hi Chris,

      this might give you some helpful informations: https://www.lifewire.com/send-email-from-php-script-using-smtp-authentication-and-ssl-1171197

      Please keep in mind, that we are not supporting SMTP from a shared webspace officially (only Sendmail). But you might try it with smtp.1and1.com and an existing 1&1 mail address + SMTP auth.

      Best,

    Hello! Can I upgrade to PHP 5.2 – 5.4 “and 5.3” ? Thanx

    1. 1and1help says:

      Hi Don,

      if you are not using PHP Extended Support for PHP 5.2 or 5.4 yet, our customer support can activate this with an additional monthly fee: https://contact.1and1.com.

      In the past we never offered PHP 5.3, so we can’t offer that.

      Best regards,
      Michael, 1&1
