Adding a mailto: link on my site, but it occurred to me that it's possible the user may not have a client set up to handle it
I found this thread from 3 years ago and was hoping there's something doable now. I don't necessarily need to figure out what's handling their mailto links, but rather if it got handled at all. Is this possible?
No. =(
The answer in your link still stands today. The knowledge that something was even capable of handling the event is way to much information to give to a browser.
