i just installed (via apt) sendmail 8.13 on my debian etch. although i am able to connect on the localhost 25. but i can't connect when i supply the global ip or my domain name.
here's wat error i get:
telnet dspace.ipu.ernet.in 25
telnet: Unable to connect to remote host: Connection refused
do i need to perform some extra configs after installation before sendmail gets ready for everything..?
