Hello,
I've searched alot in the documents, sorry if I missed anything, BUT
MY QUESTION IS:
I want to restrict Unix/Linux System user such as XYZ of using
sendmail to certain domains:
in example:
xyz.com <http://xyz.com>
xyt.com <http://xyt.com>
ztq.com <http://ztq.com>
and have it rejected if he tried to use other domains as sender
You can use a milter: http://www.postfix.org/MILTER_README.html
There is nothing native that can arbitrate locally-submitted mail (apart
from disallowing certain users to use it at all).
Somewhat preventing forgery, Is there any solution right now for
that or sendmail (postfix) should be modified?
Also is there any solution to prevent this using SASL, I tried alot
of header checking, it is possible but very messy and too many checks
are required,
SASL is used on SMTP connections; sendmail doesn't use it.
