Package: greylistd Version: 0.8.7 Severity: important Tags: patch
Bug #480365 was no bug, but intentional behaviour. After the fix of bug #480365 the behaviour changed in a way it was not intended when the options SINGLECHECK and SINGLEUPDATE were introduced.
As the comment in the config file for SINGLEUPDATE states, the single values should only be used in the WHITE state, in the GREY state there should be normal triples be used. This is because the GREY state items have to identify reappearing MESSAGES and are therefore more specific, while the WHITE state items have to identify HOSTS and therefore just use one key (the IP address usually). After the patch of bug #480365 SINGLEUPDATE will also put single values in the GREY state items, which is wrong for what was intended with this option.
The mistaken fix changed the behaviour, and the greylisting will be less effective now for all the sites using it, since different mails from the same host will now trigger the update into the WHITE state.
BTW: For the behaviour after the mistaken fix (just always using only the first key in the items) you don't need SINGLEUPDATE at all. You can just use empty values for the second and third key in the exim config.
The fix for this bug is to undo the patch of bug #480365. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
