I'd say the problem is almost certainly that your database server isn't sending a
"From:" field in the E-mails. You should check that software to see what it is doing.
Remember that there is nothing preventing you from sending an E-mail with no "From:"
field (all that the SMTP server cares about is the "MAIL FROM:" in the message
envelope, which is typically not shown in the headers).
Check an E-mail that is sent to the local server. See first if the From: header is
there. If not, your database server app is definitely at fault. If it IS there, see
if there is a "Received:" header below it -- if so, the database server app is still
at fault (it got added in by a mail server later from the envelope "MAIL FROM:"
header).
