I am using the server as an smtp server. It means all clients (let's say 192.168.1.20/25) in my lan send mails throughout my server (let's say 192.168.1.1) which is obviously directly connetted to internet.
(when i say clients i mean for instance outlook express, not other standalone servers).
To let these clients relay I have for any IP an entrance in the access like this:
localhost.localdomain RELAY 192.168.1.20 RELAY
Now, what i wonder is why sendmail allows relay even if I remove these entries. and only does not allow relay if i remove from hosts the hostname i gave to the machine (e.g. 192.168.1.20 lan01)
About this i guess is because if I remove the hostname the ip does not resolve so the server does not accept it. So the fact i does not relay has nothing to do with the access database or access rules in general.
Anyway why if I remove the 192.168.1.20 RELAY line that machine is still able to relay?
I obviously run makemap and restart sendmail after having modified access file and i don't have relay-domains entries (only localhost)
Thanks PAUL i appreciate your help and i hope i was clear enough

i also realized that sendmail allows relay from any host in /etc/hosts no matter if the host is listed in the access file. is this normal?
i mean for all the other hosts (from internet) the relay is not allowed isn't it?
sendmail does not allow relay from any host in /etc/hosts; it allows relay from any host with a RELAY tag in the access.db, and to any domain listed in /etc/mail/relay-domains
What makes you think it allows relay from any host in /etc/hosts?
