Email Client doesn't show "From Name" dynamically

When someone submits me a form, I want his name to appear into the email (email heads?).
I was able to show his/her email address in Thunderbird or Outlook "from email" field, by using submitter's email "field name" into "Dynamic from email" for the email action at Administrator (or form's recipient). I guess it was possible because the field name is was only one word "email".
However, I can't do the same for his First and Last name.
I am filling the "Dynamic from name" with:
First Last
or
{First} {Last}

with no success.

What can I do?


ps. While I was trying to fix this, I saw there was a name like "Root Localhost". what is this?

ps2. I am aware that "Dynamic from email" is a reason for spam, but because I use it only for our email clients (Outlook or Thunderbird), I guess this is not a problem, right?

same goes for Dynamic reply to name and Dynamic reply to email. I m having success to the recipient's email address, but failure to show his name.

Hi jdran,

Please see this FAQ - the same method will work to build a name from first and last name.

Root:localhost or similar names may show up when the From Name is empty.

I strongly recommend that you do *not* use the Dynamic From Email element in your Email Setups. Using this often results in your emails being marked as spam and dropped into a spam filter. Instead use the static From Email with an address that matches the site domain name and use Dynamic ReplyTo Email for the user email. The result is the same but with a much better chance of good delivery.

Bob thanks for your reply.
I need some clarification about the spam issue you say.

I only use Dynamic From email element on "Admin" area. i don't use it for Clients.
So, according to the above, would it be ok if I use Dynamic From Email and tell my co-workers to mark as "No Spam" any email comes from Chronoforms??
or there will be a problem with clients too? (I repeat; I don't use Dynamic From Email element to them)

Thanks

Hi jdran,

It depends on your mail service - test it and see what happens. I still recommend that you don't use the Dynamic From though.
