Tracking does not support wildcard characters or regular expressions. Tracking 
searches are not case sensitive.

You can use the following search parameters when you run a message tracking 
query:

Envelope Sender: Select “Begins With,” “Is,” or “Contains,” and enter a text 
string to search for in the envelope sender. Valid parameter values are email 
addresses, usernames, and domains.

Envelope Recipient: Select “Begins With,” “Is,” or “Contains,” and enter 
text to search for in the envelope recipient. Valid parameter values are email 
addresses, usernames, and domains.

If you use the alias table for alias expansion, the search finds the expanded 
recipient addresses rather than the original envelope addresses. In all other 
cases, message tracking queries find the original envelope recipient 
addresses.
