About storage estimation for extended reports
You can generate reports according to the information that Symantec Message Filter logs. Symantec Message Filter maintains statistics for your site in the MySQL database. This data is the basis for the standard reports that indicate total spam filtered and total virus filtered (if applicable).
You can also track the following data:
Sender domains
Senders
Sender HELO domains
Sender IP connections
Recipient domains
Recipients
Table: Potential effect on storage of report data storage types describes the effect on storage for each data storage type.
Table: Potential effect on storage of report data storage types
Email envelope data storage type | Estimated effect on storage | Spammers are capable of falsifying | Description, effect on storage, and example |
|---|
Sender domains
| High
| Yes
| This data storage type is the domain that sends the message.
Because spammers can forge this information, many unique sender domains can be received each hour.
Example:
symantecexample.com
|
Senders
| High
| Yes
| This data storage type is the message sender user name. Sender domains information is also stored if the Senders check box is selected on the Reports Settings page.
Because spammers can forge this information, many unique sender user names can be received each hour.
Example:
ana9a5b3c@symantecexample.com
|
Sender HELO domains
| High
| Yes
| This data storage type is the sending domain listed in the HELO/EHLO SMTP command.
Because spammers can forge this information, many unique sender user names can be received each hour. Also, if users at your company receive a lot of messages from outside your company, many unique sender HELO domains can be received each hour.
Example:
symantecexample.com
|
Sender IP connections
| High
| Rarely
| This data storage type is the IP address of the SMTP client that has contacted the local MTA.
If users at your company receive a lot of messages from outside your company, many unique sender HELO domains can be received each hour.
Example:
172.16.0.0
|
Recipient domains
| Low
| No
| This data storage type is the domain that is the message.
Unless your mail server receives email for more than approximately five domains, the effect of selecting this data storage type is likely to be low.
Example:
symantecexample.com
|
Recipients
| Medium to high
| No
| This data storage type is the message recipient user name. Recipient domains information is also stored if the Recipients check box is selected on the Reports Settings page.
The effect on storage depends on the number of users at your company. Effects on storage also depend on whether this data storage type is selected in combination with another data storage type.
Example:
jdoe@symantecexample.com
