I was wondering if anyone that knows sendmail well enough to say if
something like this can work?
/etc/mail/access
192.168.0.1 RELAY
192.168.0.2 RELAY
192.168.0.0/24 REJECT
Sendmail doesn't understand CIDR format in the access file. You'd need
to use:
192.168.0 REJECT
as it implies, I want to allow only certain hosts to send outgoing
email, while rejecting all others, even if authentication is used.
However internal email should still be allowed.
Is there a way to do it?
How would you propose to distinguish between "internal" and "outgoing" mail?
The easiest way of doing this is probably to run two mail servers, one
handling only internal mail, accessible to all, and one capable of
outgoing mail, available only to the selected few.
