"From" is the same as "To"

Hmm I tested the current HEAD for smtp and its not giving me this issue, when using the core contact form. Please update to the latest dev release and see if it makes a change?

My debugging below:

CURRENTUSERMAKINGCONTACT --> the admin user's email address
USERGETTINGCONTACTED --> is the user (Samuel Adamson's email I changed in Umami)
SITEINSTALLADDRESS --> The Site install address

(Note, if i click 'send yourself a copy' then the From and To are the same, which is expected)
