Good day!
What's the meaning of this message relayed back by GMail. Our email
server can accept and deliver email from our local clients (Outlook),
but emails from outside (i.e. gmail.com) is not accepted. Below is the
excerpt of the message received:
From: Mail Delivery Subsystem <[EMAIL PROTECTED]>
Date: Mar 17, 2006 5:04 PM
Subject: Delivery Status Notification (Failure)
To: [EMAIL PROTECTED]
This is an automatically generated Delivery Status Notification
Delivery to the following recipient failed permanently:
[EMAIL PROTECTED]
Technical details of permanent failure:
PERM_FAILURE: SMTP Error (state 9): 550 5.7.1 <[EMAIL PROTECTED]>...
Relaying denied
What could be the problem here? I'm a newbie about MTAs and lately was
tasked to manage this mail server.
For the system configuration background, our office network is
protected from outside by an OpenBSD 3.8 invisible firewall. Our MTA
is qmail-1.03, running on Whitebox Enterprise Linux 3.0 (Respin 2).
This mail server was OK until this week, this firewall was running for
almost a month and I've no idea what could be wrong.
Your help will be highly appreciated. Thank you very much in advance.
