Dear all,
I am a newbie in Postfix. I have successfully installed postfix in
ubuntu refers the tutorials:
https://help.ubuntu.com/community/Postfix
Tutorials often fail to explain how it actually works. Don't depend on them.
now I could send mail internally, but could not send mail to the
outside (gmail.com, yahoo.com, etc).
the Mail Delivery Status Report is as follows:
-------------------------
The mail system
<x...@gmail.com>: unknown user: "xxx"
"Unknown user" is clear enough.
[-- Attachment #2: Delivery report --]
[-- Type: message/delivery-status, Encoding: 7bit, Size: 0.3K --]
Reporting-MTA: dns; xxx.cewit.stonybrook.edu
X-Postfix-Queue-ID: BA73BA070A
X-Postfix-Sender: rfc822; r...@xxx.cewit.stonybrook.edu
Arrival-Date: Tue, 19 Oct 2010 14:25:22 -0700 (PDT)
Final-Recipient: rfc822; x...@gmail.com
Action: failed

Diagnostic-Code: X-Postfix; unknown user: "xxx"

The logs of that message would provide more insight into what happened.
It seems the error msg was sent from your local host instead of
gmail.com <http://gmail.com/>
Is that in the DSN or are these your words ?
I already tries to "Indirect delivery via the local delivery agent"
refers to:http://www.postfix.org/MAILDROP_README.html.
How postfix delivers local mail has little or nothing to do with remote
MTAs.
If you can provide logs for such a message, it is fairly simple to
determine what happens.
