Introduction to Exchange 2003 Server - NDR (Non-Delivery Report)
Cleaning up NDR stuffed mail queues by Chris Lehr
I came upon this, and was shocked it was not publicized more. Microsoft released a small utility a while ago called aqadmcli.exe. It's a command line interface for SMTP queue management. When a domain gets
spammed a lot, many NDR's or non-delivery reports can occur, filling the queue with messages that may never get delivered. This utility allows you to set flags, and delete messages based on these flags. For
example, you can use it to delete all mail with the "FROM" being "postmaster@yourdomain.com" to remove (very very quickly compared to the GUI ESM tool) all emails sent from postmaster@yourdomain.com (which
are most likely all the NDR's that are clogging their SMTP queue. See more about Chris Lehr thoughts on Exchange

Guy Recommends: SolarWinds Engineer's Toolset v10
The Engineer's Toolset v10 provides a
comprehensive console of utilities for troubleshooting computer problems. Guy says
it helps me monitor what's occurring on the network, and the tools
teaches me more about how the system literally operates.
There are so many good gadgets, it's like having free rein of a
sweetshop. Thankfully the utilities are displayed logically: monitoring, discovery, diagnostic, and Cisco tools.
