Hi a long-time issue before this was forked into a different repo:
It is not possible to use the following syntax,
&emailFrom=[[+field10]]
See http://forums.modx.com/thread/79957/formz-emailtpl
It would be nice it this could be implemented.
And without the above syntax added to the snippet call, it would be nice if when you received an email from your website contact form if clicking reply sent the message back to the sender. At the moment clicking reply goes back to the modx admin user.
Thanks for any help with this, I posted on the Modx forum about this here for full details of what I have tried:
