Top Sender HELO Domains All Top Sender HELO Domain reports are affected
Top Sender IP Connections All Top Sender IP Connections reports are affected
Top Succeeded Connections SMTP report
Top Failed Connections SMTP report

The process of IP selection described in the "Sender HELO domain or IP connection shows gateway information" issue of the "Table: Report data details" section of the article HOWTO53390 is applied to all messages regardless of direction.
The IP address of 255.255.255.255 is used to indicate that the receive headers could not be parsed successfully.
This is by design.
