You can set it in “Admin Email Message Options”.
It seems it doesn’t work 🙁
Maybe because I’m using “Postman SMTP” Plugin and it sends it through my Gmail account.
But… I set the Sender Name in Postman SMTP Plugin and it works when I send the test email. CForms seems to ignore this setting and the email gets sent with my bare gmail address in the FROM field 🙁
Postman will honour the From field set by the creator of the email. The from field contains the From address and an optional name like this:
jason@gmail.com
Jason <jason@gmail.com>
Some plugins, like contact forms, set the From field to the email address of the visitor instead.
Visitor <visitor@gmail.com>
Servers like Mandrill accept this behaviour. Servers like Gmail see this as Spoofing and do not accept it. They will revert the from address back to your own like this:
Visitor <jason@gmail.com>
The Session Transcript in Postman’s Email Log (Tools > Email Log) will show exactly what was sent to the server.
