Hi Julian,
Have you also tried sending email from a non-root account? The root
user is "exposed" by default in Sendmail. This means that the root user
will *NOT* be masqueraded or remapped through genericstable. You can
see that the root user is exposed by looking at the {E} class:
gothmog:/etc/mail# grep '{E}' sendmail.cf
C{E}root
Try sending email from a different local user or remove the root user
from the {E} class (by manually editing sendmail.cf and restarting
Sendmail).
