Just installed a new 7.5.3 site, and new users are getting the registration "Thank you for registering" email with the from address showing:
From: UnknownSender@UnknownDomain
So it gets dumped by their spam filters.
I cannot find what/where I need to change anything.
If I use the "Notify moderator" function, the email shows coming from the admin email address.
In my CP, Primary Settings, Advanced Options, Use specified SMTP Server, the field is blank. Should that be set?
Thanks for the help.
