I added this line to my wpmu-functions.php file at the end of the newuser_notify_siteadmin function
$headers = 'From: Calvin Micklefinger <email@example.com>' . "\r\n\\"; wp_mail('firstname.lastname@example.org', 'subject', 'message', $headers);
I would have expected that as simple as that is, the email "From" would have said
Calvin Micklefinger <email@example.com>
As limited as my coding skills are, I really don't see much choice for any other response.
What I got was
Why in the Sam Hill is that happening? Where do I look to find a solution? This is also disrupting a very solid and well respected plugin I use.
