the email log ninja !

Often the poor Administrator is faced with questions like;-

• I sent it, it never arrived, Why
• I'm not getting any mail from blah blah@blah
• and the ultimate - my email is not working right

Alas Users always seem to see a different screen and attempts to replicate issues often end in failure, this generally brings no credit to the expert Administrator and is often met with;-

"well it wasn't working yesterday"  :-)

Enter the email log ninja !

Email log search gives administrators the ability to sift through the last month of delivery logs for their domains and evaluate message transit. This is useful for tracking down a sender or recipient's missing messages and identifying their route to your users' inboxes.
