Why postfix reject outlook to send mail(always says relay denied)?
Now, I am trying to setup my company email system with postfix/dovecot .
Unfortunately, the system always complain as
"Relay denied" when I try to use outlook express to send mail to firstname.lastname@example.org.
I have pasted the maillog and packet trace file here.
Can you help me to figure it out??
Note: For the packet trace, you just open it with wireshark(Change the extension from zip to pcap)
