Traffic Service provides server administrator a way to control incoming/outgoing email traffic and preserve CPU and other computer resources. By default, Traffic Service is stopped, and it can be started at Web Access->Service. After the service is started, the time interval for traffic service should be defined, as all email traffic count is based on this time interval. For example, if the time interval is set to 15 minutes and the email count limit from a single user is set to 100, users are not allowed send more than 100 emails in 15 minutes.
Incoming Traffic Control
Incoming traffic rules limit the email traffic from outside IP address to the SMTP service. It doesn't count the email traffic from authenticated user.
Incoming traffic rule syntax:
[IP address (*,? wildcard is supported)]:[Message Count]/[Message Size(MB)]
For message count and message size, 0 means unlimited. You can define multiple rules,
every line presents a rule.
Usage Example:
The following rules limit: The email count is less than 100, and the total size of all emails is less than 20MB from 192.168.0.1 in the time interval. The email count is less than 300, and the total size of all emails is unlimited from 127.0.0.1 in the time interval.
The following rules limit: The email count is less than 100 and the total size of all emails is unlimited from every IP address but it doesn't limit the email from 192.168.0.1.
Note: The email count and email size is counted based on recipients count. For example: an email size is 1024KB, but it contains 20 recipients, then it yields 20 email count and 20 * 1024KB = 20MB email size.
Outgoing Traffic Control
The outgoing traffic rules limit the email traffic from authenticated user to outside domain. It doesn't count the email traffic to local domain.
The outgoing traffic rule syntax:
[user email address | domain (*,? wildcard is supported)]:[Message Count]/[Message
Size(MB)]
For message count and message size, 0 means unlimited. You can define multiple rules,
every line presents a rule.
Usage Example:
The following rules limit: The email count is less than 100 and the total size of all emails is less than 20MB from every user of emailarchitect.com in the time interval. The email count is less than 300, and the total size of all emails is unlimited from test@emailarchitect.com in the time interval.
The following rules limit: The email count is less than 100 and the total size of all emails is unlimited from every user but it doesn't limit the email from test@emailarchitect.com.
The following rules limit: The email count is less than 1000 and total size of all emails is less than 100MB from the domain "emailarchitect.com".
Note: The email count and email size is counted based on recipients count. For example: an email size is 1024KB, and the email contains 20 recipients, in total it yields 20 email count and 20 * 1024KB = 20MB email size. This rule set doesn't apply to the email to local domain. For example, if user@emailarchitect.com sends an email to user2@emailarchitect.com, the traffic of this email is ignored.
Once the limit is reached, authenticated user can not send email to outside domains, "Too many outgoing traffic" error will be returned by SMTP service or Web Mail when user try to send the email to outside; however, the user can still send email to local domain.
