Sendmail Masquerade Problem

[Alex de Kruijff]

I have problem with sendmail that is giving me a headake. I can send
mails als long when I give the from adres, but when I leave this out the
server enters the localname and my ISP isn't accepting the mail. (i.e.
echo 'test' | mail -vs test to at mail.com -ffrom at mail works, but without
the -f option it gets accepted but is rejected by the isp) I have
masquerade setup, but that doesn't seem to do the trick. However check
on shows that it handeled oke.



I added to private.mc

I found in private.cf

C{M}localhost
C{M}localhost.lan
C{M}private
C{M}private.private

# who I masquerade as (null for no masquerading) (see also $=M)

Running "sendmail -d0.1 -bt </dev/null" gives me
