I see there's "mailto.php?emailaddress=", but it doesn't handle complicated mailto URI data very well or to my liking.

Attached is mailto_protocol_handler2.php. I used mailto.php as a reference.

It produces the exact results I want it to. There are just 2 problems.

1. How do I load compose.php in the right frame AND get compose.php to use ?send_to=&body= etc. like it does when not loaded in a frame?

2. When the user is not logged in, I want to redirect to login.php and retain the send_to=&body= etc. data after the user logs in.

mailto.php does these things, but it uses ?mailtodata=, which uses some funky data format that's percent-encoded, which compose.php decodes etc.

How do I make things work with "send_to=" etc. or how to I convert the to, cc, bcc, body and subject percent-encoded hvalues that I've built into something that ?mailtodata= understands?

If you look at mailto.php, I basically want to support the !$compose_only and $force_login features.

I'm doing this with 1.4.x

Thanks

On a side, when I have a signature set, SM inserts a blank line at the top of the body. How can I remove that?

mailto_protocol_handler2.php (application/octet-stream, 4 KB)

<?php

/**
 * mailto_protocol_handler2.php
 *
 * This page accepts a percent-encoded mailto URI (via ?uri=) that was 
 * generated by HTML5's registerProtocolHandler and converts the data 
 * into the format that compose.php?send_to=&subject=&body=&cc=&bcc= 
 * requires to fill in the compose form's fields.
 *
 * <https://developer.mozilla.org/en/DOM/window.navigator.registerProtocolHandler> 
 * <http://www.whatwg.org/specs/web-apps/current-work/#dom-navigator-registerprotocolhandler>
 *
 * This handler takes duplicate hvalues in the mailto URI and joins
 * them according to the following rules.
 *
 * to, cc and bcc: Join all non-empty hvalues with %2C%20.
 *
 * subject: Use only the last subject hvalue, even if it's empty.
 *
 * body: Join the first non-empty hvalue and all hvalues after that
 * (even if they're empty) with %0D%0A.
 *
 * Unsafe %HH like %00 in the mailto URI are percent-encoded so they
 * come out literally in the field.
 *
 * Newlines are removed from the to, cc, bcc and subject hvalues
 *
