  • “Uploads are disabled” on some mobile devices.

Some devices cannot upload files. According to Modernizr :

iOS < 6 and some android version don’t support uploads.

File uploads are disabled for ancient IOS 5 devices. Please add a support message if uploads are disabled on your phone or tablet, so I can remove the upload button if your device is detected.

Address Validation
  • Address validation is an option to check recipient domain on manually entered addresses.

  • International (non-ASCII) domains must be converted to punycode with idn_to_ascii.

    Unfortunately, idn_to_ascii is not available on all systems.

  • “Cannot verify international domains because idn_to_ascii function not found”

    This is displayed when Quick Mail cannot verify domains containing non-ASCII characters.

  • checkdnsrr is used to check a domain for an MX record.

    An MX record tells senders how to send mail to the domain.

Mail Errors
  • Quick Mail sends email with wp_mail.

    wp_mail error messages are displayed, if there is a problem.

  • “You must provide at least one recipient email address.”

    wp_mail rejected an address. Seen when Quick Mail verification is off.
