Lock down Sendmail
I have a linux server running SENDMAIL 8.13.3, config V10/Berkeley
I tested it for an open relay and it came back negative, I need to know how to setup the server to just accept emails to domains that are listed under Local Domains (CW)
So basically any email that arrives at the server and it's not for one of the domains at (CW) gets rejected or discarted. But I have some domains that forward mail out so I need to allow the server to send mail from the local domains to outside servers ex user@domain1.com has a virtuser rule to forward emails to user1@hotmail.com
Does anyone know how to do that?
Thanks

EE has a sendmail-specific TA --> https://www.experts-exchange.com/Networking/Email_Groupware/Sendmail/
Whoops! I thot I was looking at a different TA. Ignore my last Comment.
you have a file called /etc/mail/relaydomains
you can specify a list of domains
.domain.com RELAY
.domain2.com RELAY
this would make the server relay only for these specific domains

It's working now it's relaying the domains I need, without adding to /etc/mail/relaydomains, I need to find out how to block any email that is not going to a local domain... Somehow that's is happening on my server...
I have over 20 emails like this on queue now
