Hello dear community, again hehe. SUSE10 server user here.
We have an utgent issue with our External SMTP traffic, it all bounces with the code 553 (#5.7.1).
Any idea on where to start the troubleshooting? I have one clue though, in the morning hours before this happened, a user was buffering over 8GB of data via our internett connection.
I would post this on the Novell forums, but this url sends me to a timeout: http://www.novell.com/common/util/secure/login.php?r=http://forums.novell.com/

Hi abates1,
you have provided not that much technical details, so I need to be rather general in my response, sorry for that.

How about starting with the mail server that creates the 553 - if it’s postfix on the SLES10 box, you ought to find more details listed in the logs of that machine.
553 is “relaying denied”. In the thread title you talk about outbound emails - is this an initial setup our was this working before? Are there any new/changed configuration files on the reporting mail server? How have you set up your sender restrictions (user login, client machines per IP ranges/DNS names, sender email domain or anything else?
What mail server are you using? Could you tell us more about a specific (test) email - i.e. mail server logs for that test message?
With regards,
Jens
