Keeping track of how many messages are accepted, relayed on to domains for which we are the primary or secondary MX server, or which are blocked. Then specify for the blocked messages what the reason for blocking was. All that aside we also keep track of how many messages were determined to contain a virus, or were later detected or considered to be junk mail of some sort.
The stats show the past 3 weeks, and monthly summaries of the past 2 years, currently, but I’ve been tracking the data for longer than that. To be precise:
- The whitelist/spam/block/etc stats go back to August 2003.
- The virus stats begin in July 2004.
- The Thunderbird Junk folder stats began in October 2005.

| No such user | Email delivery attempts that were rejected because the user does not or no longer exists. |
| No such domain | Email delivery attempts that were rejected because the domain of the envelope sender did not resolve. |
| No relaying | Attempts at trying to use our server for relaying for domains other than the ones that it has been configured for. |
| Virus detected | A virus had been detected and the message has been forwarded to a dedicated (safe) quarantine location. |
