I’ve been looking throughout the Internet today looking for ways to get mailto: links to work with Firefox and Zimbra. Since I didn’t want to touch the registry and most of the people here use Macs anyway, I had to make a Greasemonkey script to do the job. Sure, there are already scripts to do this, but they point to the standard interface. I wanted the advanced interface.

First, take this code, put it in a text editor, and change “mail.server.com” to your zimbra server (2 instances).


// ==UserScript==
// @name Mailto Compose In Zimbra
// @namespace http://www.dawnbreaker.com
// @description Rewrites "mailto:" links to Zimbra compose links
// @include *
// @exclude https://mail.server.com
// ==/UserScript==
(function() {
var processMailtoLinks = function() {
var xpath = "//a[starts-with(@href,'mailto:')]";
var res = document.evaluate(xpath, document, null,
XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE, null);
var linkIndex, mailtoLink;
for (linkIndex = 0; linkIndex < res.snapshotLength; linkIndex++) {
mailtoLink = res.snapshotItem(linkIndex);
//alert(mailtoLink.href);
var m = mailtoLink.href;
var matches = m.match(/^mailto:([^\?]+)(\?([^?]*))?/);
var emailTo, params, emailCC, emailSubject, emailBody;
emailTo = matches[1];
//alert("Found to=" + emailTo);
params = matches[3];
if (params) {
var splitQS = params.split('&');
var paramIndex, param;
for (paramIndex = 0; paramIndex < splitQS.length; paramIndex++) {
param = splitQS[paramIndex];
nameValue = param.match(/([^=]+)=(.*)/);
if (nameValue && nameValue.length == 3) {
// depending on name, store value in a pre-defined location
switch(nameValue[1]) {
case "to":
emailTo = emailTo + "%2C%20" + nameValue[2];
break;
case "cc":
emailCC = nameValue[2];
//alert("Found CC=" + emailCC);
break;
case "subject":
emailSubject = nameValue[2];
//alert("Found subject=" + emailSubject);
break;
case "body":
emailBody = nameValue[2];
//alert("Found body=" + emailBody);
break;
}
}
}
}
mailtoLink.href = "https://mail.server.com/zimbra?app=mail&view=compose" +
(emailTo ? ("&to=" + emailTo) : "") +
(emailCC ? ("&cc=" + emailCC) : "") +
(emailSubject ? ("&subject=" + emailSubject) : "") +
(emailBody ? ("&body=" + emailBody) : "");
// mailtoLink.onclick = function() { location.href = newUrl; return false; };
}
}
window.addEventListener("load", processMailtoLinks, false);
})();

Then paste the code into the generator here: http://arantius.com/misc/greasemonkey/script-compiler

Leave the GUID as it is, change the max version to 3.5.* and then add anything else you might want.

Compile the script and then install the .xpi file into firefox.
