• RFC 2368 - The mailto URL scheme

Description:

A mailto</code> URL used on your site tries to specify an unknown header. Although the syntax defined in RFC 2368 allows any header to be specified, in practice only a small subset of headers will work in most browsers. The subset of headers that will work in most cases are: <code>to, cc, bcc, subject and body.

Example:

<a href="mailto:sales@example.com? sender=form@example.com">

Standards:

• RFC 2368, section 2 - The mailto URL scheme

Description:

A mailto URL used on your site contains a bad option.

The options section of a mailto</code> URL must consist of pairs of names and values, the name separated from the value by an <code>=</code> character and each pair separated from the next by an <code>&amp; character.

Example:

<a href="mailto:sales@example.com?subject">
