I use email send through smtp server, and a test list message gets a nice DKIM valid header.
However, when a request for confirmation registration email is send, it seem to go with normal php sendmail?
I get DKIM errors in this mail : dkim=neutral (body hash did not verify)
?
Ok, error went away when I added a default system html template. Now DKIM verifies.
But, now, whatever I change in settings for “Message subscribers receive when they sign up” nothing changes in the actual mail send 
Well edited the database directly
have subscribemessage:1 and subscribemessage (f.i)
No idea how to get thos to show in the admin prog
