Each URL click tracking log consists of email message information and URL
click information. Email message information, including
Sender, Recipient(s)
and Message ID, is generated by IMSS, and URL click information,
including Timestamp, URL,
Blocked, Warned and
Clicked Through, is obtained from the
Time-of-Click Protection service. IMSS combines information from the
two sources before providing logs for query.
If you find email message related fields shown as not available in query
results, the possible reasons are as follows:
-
IMSS stores email message
information only for a certain period of time, which can be
configured in log settings. If a user queries logs whose email
message information is outdated but URL click information does
not expire without specifying any field, those logs will be
shown in query results, but the email message related fields
will be regarded as not available. However, if a user queries
such logs by specifying any of the email message related fields,
those logs will not shown because IMSS cannot match the
specified field values.
-
Each IMSS server has its
own email message information for logs, while URL click tracking
logs are generated by Activation Codes. If multiple IMSS servers share one
Activation Code, an IMSS
server might hold logs whose email message information belongs
to other IMSS servers.
When a user queries logs on that server, the situation is
similar to that described for outdated email message
information.
