hi all, running centos 4.7 i686.
I seem to have an o pen r elay sendmail server. How do I close it?
I have the STRAIGHT centos install sendmail.mc file. Only thing I changed was: dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl
so as to allow incoming email and not just localhost. however this seems to relay everyone.
I looked at http://www.sendmail.org/tips/relaying but it just talks about (AFIKT) enabling specific relays to occur - not how to CLOSE the relaying.
How do I close the relay?
