Previously Exim might Removing the spurious timestamps from the process log simplifies exiwhat. +TF/04 Improved ratelimit ACL condition. + + The /noupdate option has been deprecated in favour of /readonly which + has clearer semantics. The /leaky, /strict, and /readonly update modes + are mutually exclusive. The update mode is no longer included in the + database key; it just determines when the database is updated. (This + means that when you upgrde Exim will forget old rate measurements.) + + Exim now checks that the per_* options are used with an update mode that + makes sense for the current ACL. For example, when Exim is processing a + message (e.g. acl_smtp_rcpt or acl_smtp_data, etc.) you can specify + per_mail/leaky or per_mail/strict; otherwise (e.g. in acl_smtp_helo) you + must specify per_mail/readonly. If you omit the update mode it defaults to + /leaky where that makes sense (as before) or /readonly where required. + + The /noupdate option is now undocumented but still supported for + backwards compatibility. It is equivalent to /readonly except that in + ACLs where /readonly is required you may specify /leaky/noupdate or + /strict/noupdate which are treated the same as /readonly. + + A useful new feature is the /count= option. This is a generalization + of the per_byte option, so that you can measure the throughput of other + aggregate values. For example, the per_byte option is now equivalent + to per_mail/count=${if >{0}{$message_size} {0} {$message_size} }. + + The per_rcpt option has been generalized using the /count= mechanism + (though it's more complicated than the per_byte equivalence). When it is + used in acl_smtp_rcpt, the per_rcpt option adds recipients to the + measured rate one at a time; if it is used later (e.g. in acl_smtp_data) + or in a non-SMTP ACL it adds all the recipients in one go. (The latter + /count=$recipients_count behaviour used to work only in non-SMTP ACLs.) + Note that using per_rcpt with a non-readonly update mode in more than + one ACL will cause the recipients to be double-counted. (The per_mail + and per_byte options don't have this problem.) + + The handling of very low rates has changed slightly. If the computed rate + is less than the event's count (usually one) then this event is the first + after a long gap. In this case the rate is set to the same as this event's + count, so that the first message of a spam run is counted properly. + + The major new feature is a mechanism for counting the rate of unique + events. The new per_addr option counts the number of different + recipients that someone has sent messages to in the last time period. It + behaves like per_rcpt if all the recipient addresses are different, but + duplicate recipient addresses do not increase the measured rate. Like + the /count= option this is a general mechanism, so the per_addr option + is equivalent to per_rcpt/unique=$local_part@$domain. You can, for + example, measure the rate that a client uses different sender addresses + with the options per_mail/unique=$sender_address.
