Some of the more rarely used lookups are performed only when needed, which is a possible reason for not seeing a lookup for spam_dsn_cutoff_level in the debug logging. For example, if no DSN is being sent, or if it is being suppressed for some other reason even before it reaches a code which is considering dsn cutoff. There are four variables controlling DNS suppression, two for by_sender vs. by_recip, times two for believable vs. possibly-faked sender address (search for 'crediblefrom' in release notes): @spam_dsn_cutoff_level_maps @spam_dsn_cutoff_level_bysender_maps @spam_crediblefrom_dsn_cutoff_level_maps @spam_crediblefrom_dsn_cutoff_level_bysender_maps Of these four, only the first one has its SQL field 'spam_dsn_cutoff_level'. The rest of them only do statical lookups (no SQL or LDAP equivalent). This may look like a limitation, although I consider suppressing DNS rather a site manager's decision and not a recipient's decision, so in this view even the 'spam_dsn_cutoff_level' SQL field can be considered redundant/undesirable. The default for setting sender as 'credible' is for originating mail (outgoing or internal-to-internal), or when a valid DKIM signature is made by a domain matching envelope sender domain. Custom hooks may supply other/additional criteria. If the 'sender is credible' flag is turned on, only lookups on: @spam_crediblefrom_dsn_cutoff_level_maps @spam_crediblefrom_dsn_cutoff_level_bysender_maps are performed, which may be another reason why you are not seeing SQL lookup in debug logging. > If you think it's not the right way to post a question just let me know... > I'm new and not used to users lists It is the right way.
