when i tested the server ,i saw something like this:
c:>telnet 192.168.1.10 25
the email address email@example.com does not exist,i am sure the email address firstname.lastname@example.org received the test mail.
220 centos.test.org ESMTP Postfix
354 End data with <CR><LF>.<CR><LF>
250 Ok: queued as 2E2315644E4
did this show that my server is openrelayed?
postfix has configed for sasl_auth,why the ehlo command not show that ?why i can not see:
250 auth xxxxxx
