Ddclient uses sendmail as system to send mail.  The used syntax is:

This prevents issues with different version of mail and mailx.  So
currently there is no way to set the sender, although it should be
handled correctly by sendmail.  In my case I use exim which seems to
honour the configuration I did to set the from address.

You can just edit the ddclient perl script and add a from line to the
sendmail routine.  That should work, although I never tested it.

Kind regards,
