want to know how my machine in sending a mail
I am using a SLES 10 machine which was not configured by me. I am able to send mails from that machine but don't know which MTA it is using. I tried to look which service is listening on port 25 and found it was postfix. Then I checked main.cf file, but there is no configuration, But still I am able to send mails using mail or nail . Could someone help me with this, I can copy the contents of main.cf here is someone wants that.
