Chapter 6      Tracking Email Messages
  Searching for Email Messages
Note
Tracking searches do not support wildcard characters or regular expressions. Tracking searches 
are not case sensitive.
Envelope Sender: Select Begins With, Is, or Contains, and enter a text string to search for in the 
envelope sender. You can enter email addresses, user names, or domains. Use the following formats:
For email domains: 
example.com[203.0.113.15][ipv6:2001:db8:80:1::5] 
For full email addresses: 
user@example.comuser@[203.0.113.15] or user@[ipv6:2001:db8:80:1::5]
You can enter any character(s). No validation of your entry is performed.
Envelope Recipient: Select Begins With, Is, or Contains, and enter text to search for in the envelope 
recipient. You can enter email addresses, user names, or domains.
If you use the alias table for alias expansion on your Email Security appliances, 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. 
Otherwise, valid search criteria for Envelope Recipient are the same as those for Envelope Sender.
You can enter any character(s). No validation of your entry is performed.
Subject: Select Begins With, Is, Contains, or Is Empty, and enter a text string to search for in the 
message subject line. 
Message Received: Specify a date and time range for the query using “Last Day,” “Last 7 Days,” or 
“Custom Range.” Use the “Last Day” option to search for messages within the past 24 hours, and 
use the “Last 7 Days” option to search for messages within the past full seven days, plus the time 
that has passed on the current day.
If you do not specify a date, the query returns data for all dates. If you specify a time range only, the 
query returns data for that time range across all available dates. If you specify the current date and 
23:59 as the end date and time, the query returns all data for the current date.
Dates and times are converted to GMT format when they are stored in the database. When you view 
dates and times on an appliance, they are displayed in the local time of the appliance.
Messages appear in the results only after they have been logged on the Email Security appliance and 
retrieved by the Security Management appliance. Depending on the size of logs and the frequency 
of polling, there could be a small gap between the time when an email message was sent and when 
it actually appears in tracking and reporting results.
Sender IP Address: Enter a sender IP address and select whether to search messages or to search 
rejected connections only. 
An IPv4 address must be 4 numbers separated by a period. Each number must be a value from 
0 to 255. (Example: 203.0.113.15).
An IPv6 address consists of 8 sets of 16-bit hexadecimal values separated by colons. 
You can use zero compression in one location, such as 2001:db8:80:1::5
Message Event: Select the events to track. Options are Virus Positive, Spam Positive, Suspect 
Spam, contained malicious URLs, contained URL in specified category, DLP Violations (you can 
enter the name of a DLP policy and select violation severities or action taken), DMARC violations, 
Delivered, Advanced Malware Protection Positive (for malware found in an attachment), Hard 
Bounced, Soft Bounced, currently in a policy, virus, or outbreak quarantine, caught by message 
filters or content filters, and Quarantined as Spam. Unlike most conditions that you add to a tracking 
query, events are added with an “OR” operator. Selecting multiple events expands the search.
