    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
