Mail Statistics Summary

The interface divides the list into the following sections:

Grand total summary

This section displays statistics about the total number of messages messages that your server sends and receives, as well as all of the accounts that your server hosts. 

The interface displays this information across seven columns:

  • TOTAL — Displays whether the data corresponds to received or delivered mail.
  • Volume — The total size of the messages.
  • Messages — The total number of messages.
  • Addresses — The total number of addresses that receive or send mail.

    Note

    Due to an error in the eximstats process, this data may be faulty.
  • Hosts — The number of unique domains from which mail sends or to which it is delivered.
  • At least one addr Delayed — The number of messages with at least one recipient whose mail server delayed the message.
  • At least one addr Failed — The number of messages with at least one recipient whose mail server rejected the message.

Deliveries by Transport

This section displays statistics about the mail that your mail transfer agent (MTA) delivers, divided into three groups:

  • local_delivery — Pertains to messages that the system delivered from one user on your server to another.
  • remote_smtp — Pertains to messages that the system delivered from a user on your server to a user on another server.
  • virtual_userdelivery — Pertains to messages forwarded from a virtual user on your server to a real user. This occurs if you set up a mail forwarder.

For each of these three types of sent mail, the section displays two categories:

  • Volume — The total size of delivered messages.
  • Messages — The total number of delivered messages.
