Postfix and Multiple Network Cards
Good Day
I am setting up a server with Mailscanner etc which will have two NICS for the postfix
Therefore a customer can connect on either IP address
X.X.X.X
or
Y.Y.Y.Y
to collect mail...firstly how do I tell Postfix that it must look at both NICS ( as this machine will relay mail as well.)
The secondly I get a strange error, if I test the SMTP connection by doing the following and using telnet
[root@relay ~]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
220 COMPUCLEARING
quit
221 2.0.0 Bye
Connection closed by foreign host.
[root@relay ~]# telnet 10.20.7.160 25
Trying 10.20.7.160...
telnet: connect to address 10.20.7.160: Connection refused
telnet: Unable to connect to remote host: Connection refused
[root@relay ~]#
Therefore it works if I connect via localhost, but when i enter the localhost IP address it wont allow me to connect, why is that...??
