ad_parse_incoming_email (public)

 ad_parse_incoming_email message

Defined in packages/acs-tcl/tcl/html-email-procs.tcl

Takes an incoming message and splits it into parts. The main goal of this proc is to return something that can be stuffed into the database somewhere, such as a forum message. Since we aggressively filter HTML, the HTML tags are stripped out of the returned content. The message may have only plain text, plain text and HTML, or plain text and something else (Apple Mail uses text/enhanced, for example). To make our lives simpler we support only text/html as a special case; in all other cases the plain text is returned.

Parameters:
