Not a problem. This warning is inserted when someone tries to send mail
as someone else.
eg, on my server, I am user philip
if I connect to SMTP port and do:
MAIL FROM: tellis
...
The mail that I send will have the warning saying user philip set sender
to tellis
Basically, only trusted users like root, daemon, network can change name
Other users can change their name if they change to themselves.
from the man page:
-fname Sets the name of the ``from'' person (i.e., the
sender of the mail). -f can only be used by
``trusted'' users (normally root, daemon, and net-
work) or if the person you are trying to become is
the same as the person you are.
BTW, I have `fixed' the default man page that comes with sendmail because
it had some indentation problems on my system. If anyone wants a copy,
I'll mail it to you.
