Takes email message data and encodes it into a "mailto" url.
allows a user to send mail from IWP easily. All they need to do is use the "Open Url" script step with MailToEncode as the url. 
Note: uses UrlEncode to encode non-standard text characters so they can be sent in the url

Main benefit: you don't need to know how to use "mailto" to send an email using IWP

Note: these functions are not guaranteed or supported by Please contact the individual developer with any questions or problems.

This is my Custom Function and I want to edit it


This plug-in works perfectly on a Mac using Firefox or Safari and Apple Mail.

On Windows XP nothing happens in Firefox or IE8 with Outlook. Safari says that Windows doesn't recognise the mailto command.

If I use FMP Client 10 or 9 Advanced, I see an error 5 (Command invalid) when I run the script which does the OpenURL. This doesn't happen on a Mac.

The application is hosted on FMP10 Server Advanced running on Vista Business. Is otherwise rock solid.
