And what is that parameter for? :-?
Let me check:
master_service_disable (default: empty)
Selectively disable master(8) listener ports by service type or by
service name and type.
# Turn off only the main SMTP listener port.
master_service_disable = smtp.inet
Ah, you wanted to disable "smtp" connections at all? Mmm, I'm still a bit
confused about your goals...

Well, I cannot tell you how can this be achieved with Exim, sorry O:-)

In "both". Look:
stt005:~# netstat -an | grep :25
tcp 0 0 192.168.0.5:25 0.0.0.0:* LISTEN
tcp 0 0 127.0.0.1:25 0.0.0.0:* LISTEN
stt005:~# cat /etc/postfix/main.cf | grep inet_interfaces
inet_interfaces = 192.168.0.5, localhost
But I dunno if this kind of setup is what you need :-?
