All outbound external emails return 553 (#5.7.1)
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/se...ms.novell.com/
