Blocking IP Addresses

When a BlueTie interface user flags a message as Junk, by either using the Flag as feature or dragging the message to the Junk folder, the IP address of the sending server is recorded in BlueTie’s Complaint Table and may be blacklisted by BlueTie servers

In order to be blacklisted by BlueTie’s servers, the following criteria must be met:

1. There must be a disclosed number of complaints for one IP address.
2. All complaints must have been received during the previous 12 hours.

The blacklisting of an IP address will last for 12 hours for the first incident. Subsequent incidents will result in increased blacklisting time.

Each unique complaint drops off after 12 hours, however additional complaints during the block period will increase the time back to maximum of 12 hours until the complaints stop. For example, if a blacklisted IP address has 6 hours remaining on the BlueTie blacklist with only 1 complaint remaining in the complaints table and then an additional complaint is received; the IP address will be forced to restart a 12 hour blacklist period.  

Please note that the email sender will receive a bounceback message from the BlueTie servers.
