Greylisted Connections
This report tells you the number of allowed connections and delayed connections for all messages sent to all domains on the server, for whatever time period you specify. Blocked connections would be those that were greylisted, meaning there was a slight delay between when the message was sent and when it was actually delivered. There is also a handy chart that displays the trend line for the time period.
An administrator can change the dates of the report as well as the "Step", which means whether you want to see the report by hour, day, week, month or quarter. (Based on the start and end dates -- so a quarterly report would need a full 3 months selected.) Admins can change the chart type by clicking the chart icon next to the date, or even export the report as needed. Each column in the report is sortable, either ascending or descending, and the sort can change simply by clicking the column header.
System Admins can also switch the report from a "Trend" report, which shows the data for the server as a whole, or display information by Domain. This is called the report's "Mode". Changing the mode to display information by domain also allows a system admin to dig into that specific domain, by clicking on its name, to view the report just as a domain admin would view the report. This means the system admin can delve into individual user data simply by changing the Mode, again, to view the report by User.
The following report items are available:
- Day - The day of the week covered by the report.
- Passed - The total number of messages that passed greylisting and were delivered to the mailbox without delay.
- Blocked - The total number of messages that were delayed due to greylisting.
- Total - The total number of connections made to the domain. (I.e., SMTP, POP, IMAP, etc.)
It's also possible to export this data in CSV format for use in other applications, such as Microsoft Excel, Google Sheets, Apple Numbers, etc. To do this, simply click the page icon in the upper right hand corner of the reports page. Once clicked, you'll be able to save the data and name the file to whatever you want.
