A summary of route types found in the route-map, used for max-domains license control. The domain, addresses, and accounts refer to records in the route-map of the form route:some.domain, route:user@some.domain, and route:user@ respectively.

The license key field max-domains is a bit of a misnomer. It should have been called max-routes, but it is easier for people to think in terms of domains and in the majority of cases routing is by-domain only.

However, our logic counts all route: records, regardless of type, towards the license's max-domains, since the same amount of work is necessary to route by-domain as by-address or by-account.

While trying to send a reply back to the client, the server had an I/O error. Typical cause is "broken pipe", ie. the connection with the client was lost, most likely due to the client voluntarily dropping the connection. A lot of spamware reacts on the first digit of the response, dropping the connection as soon as it gets a 4xy or 5xy indication and ignoring the rest.

Sometimes the client might disconnect during the welcome banner, because of an option like smtp-slow-reply which impose delays. A lot of spamware is impatient and will drop the connection as a result.
