domain_maxmessagescriticalWritten by the Hubdatabase fieldHow many messages a minute may be sent to one destination domain, across every sending address.ip_maxmessagescriticalWritten by the Hubdatabase fieldThe per-address half of the limits: the same six quantities, counted for the pair of sending address and destination rather than for the destination alone.localipcriticalWritten by the Hubdatabase fieldThe sending address this rule applies to; empty means all of them.privatekeycriticalWritten by the Hubdatabase fieldThe PEM-encoded private key, stored in the cluster database in clear text.targetcriticalWritten by the Hubdatabase fieldThe destination being held — a domain, a receiving address, or * for everything the node sends.valuecriticalWritten by the Hubdatabase fieldOne address or one whole domain that mail is never delivered to.connection_minmessagesimportantWritten by the Hubdatabase fieldHow much work an existing connection must be given before the engine decides to open a second one.connection_offlinetimeimportantWritten by the Hubdatabase fieldAfter a failed connection or handshake, how long the engine stops trying that receiving address.domainimportantWritten by the Hubdatabase fieldThe destination this rule's profile applies to; empty means every destination.domain_maxconnectingimportantWritten by the Hubdatabase fieldHow many connections to one domain may be in the middle of being established at once — shipped at one.domain_maxconnectionsimportantWritten by the Hubdatabase fieldHow many SMTP connections to one domain may be open at the same time.domain_maxconnectsimportantWritten by the Hubdatabase fieldHow many new connections a minute may be opened to one domain.enforceimportantWritten by the Hubdatabase fieldNot what its name suggests: it records whether the signing algorithm was stated explicitly, and therefore whether the engine needs to ask DNS.expireimportantWritten by the Hubdatabase fieldThe moment a pause stops applying; zero means it stays until removed.flagsimportantWritten by the Hubdatabase fieldA bit field holding the console's behaviour switches — the ones with no column of their own.meaningfulimportantWritten by the Hubdatabase fieldThe companion mask to flags: one bit per switch, saying whether this profile decides it at all.patternimportantdatabase fieldWhat the receiving server said, matched against its response text.securityimportantdatabase fieldHow hard the engine tries to encrypt: never, opportunistically, required, or required with strict certificate checks.selectorimportantWritten by the Hubdatabase fieldThe label that tells a receiver which DNS record holds the public key for this signature.begindatabase fieldWith until, the period during which a rewrite rule applies; zero at both ends means always.canonicalizationWritten by the Hubdatabase fieldHow tolerant the signature is of whitespace changes in headers and body, as a pair of modes.codedatabase fieldThe SMTP result recorded for deliveries this rule stops.connection_maxidletimeWritten by the Hubdatabase fieldSeconds an unused connection is held open before being closed.connection_maxmessagesWritten by the Hubdatabase fieldHow many messages may be sent down one SMTP connection before it is closed and reopened.domain_maxidleWritten by the Hubdatabase fieldHow many established but unused connections to a domain are kept for reuse.finaldatabase fieldWhether remaining triggers are skipped once this one has matched.incomingWritten by the Hubdatabase fieldThe recipient pattern that makes incoming mail be published to a queue instead of relayed onward.maxqueueWritten by the Hubdatabase fieldHow many messages for this destination are held in the engine's memory at once.occurrencesdatabase fieldA counter the engine increments each time this forced error matches a delivery.pool_idWritten by the Hubdatabase fieldRestricts a rule to addresses in one pool.precedencedatabase fieldThe order in which rewrite rules are considered.protocoldatabase fieldThe protocol spoken to the proxy that owns the public address.timeout_connectdatabase fieldRepresentative of the seventeen per-stage timeouts: how long the engine waits at each step of an SMTP conversation.typedatabase fieldExact, substring, wildcard or regular expression.connection_featurestimedatabase fieldSeconds the engine caches what a receiving server announced in its greeting.domain_maxbytesdatabase fieldBandwidth ceiling towards one domain, counted in bytes per minute.precedencedatabase fieldNot a priority at all: the engine stamps the moment the profile was created and uses it to keep the console list in a stable order.priorityWritten by the Hubdatabase fieldWhere this signature is placed when a message is signed by more than one key.
