What you have below _needs_ to be "RELAY".

Can, or cannot?

(did you do that?)

Now start adding domains, IPs and networks for whom you will allow
relay.  For example, if you have a private LAN on 192.168.0.0/24
and/or an entire domain to relay for, then you need to add this:

192.168.0	RELAY
.mydomain.com	RELAY

Everything else will be rejected.

Ahh, you _do_ have access defined in your sendmail.mc (and
sendmail.cf) file, don't you?

I've been using sendmail for years to relay email out of many
networks, never had a problem (with spammers, or with access denied
from otherwise authorised places).  You seem to be doing something
fundamentally wrong.
