The code is loading default.prefs from the root where dspam.cgi/admin.cgi is
installed. But it checks first if the file is a symlink and if it so it will
warn you that the one it is going to load (the one in the root of
dspam.cgi/admin.cgi) could be different then the one used by the DSPAM binary
(since the binary will not read the web root but the default.prefs found in
DSPAM HOME).

uid 0 is used as the default when loading preferences with the preference
extension.

Yes.

Yes and no. The absolute last fallback is dspam.conf. If default.prefs are not
there then dspam.conf wins.
Using uid 0 with the preference extension can be very handy. Consider this
scenario here:
- You run a pure opt-in setup
- You want to set certain preferences for all but allow users to overwrite them
Then I would do the whole setup that way:
+-----+------------------------+---------+
| uid | preference | value |
+-----+------------------------+---------+
| 0 | dailyQuarantineSummary | off |
| 0 | enableBNR | on |
| 0 | enableWhitelist | on |
| 0 | fallbackDomain | off |
| 0 | ignoreGroups | off |
| 0 | ignoreRBLLookups | off |
| 0 | makeCorpus | on |
| 0 | optIn | off |
| 0 | optOut | on |
| 0 | optOutClamAV | on |
| 0 | processorBias | on |
| 0 | showFactors | off |
| 0 | signatureLocation | headers |
| 0 | spamAction | tag |
| 0 | spamSubject | [SPAM] |
| 0 | statisticalSedation | 5 |
| 0 | storeFragments | off |
| 0 | tagNonspam | off |
| 0 | tagSpam | off |
| 0 | trainingMode | TOE |
| 0 | trainPristine | off |
| 0 | whitelistThreshold | 10 |
+-----+------------------------+---------+
And preferences for user where you opt-in the user as soon you create a mailbox
for him would look like this:
+-----+------------+-------+
| uid | preference | value |
+-----+------------+-------+
| 6 | optIn | on |
| 6 | optOut | off |
+-----+------------+-------+
While another user who went into the Web UI and changed his settings to fit
more to his needs would have this here:
+-----+------------------------+---------+
| uid | preference | value |
+-----+------------------------+---------+
| 4 | dailyQuarantineSummary | off |
| 4 | enableBNR | on |
| 4 | enableWhitelist | on |
| 4 | optIn | on |
| 4 | optOut | off |
| 4 | showFactors | off |
| 4 | signatureLocation | headers |
| 4 | spamAction | tag |
| 4 | spamSubject | [SPAM] |
| 4 | statisticalSedation | 1 |
| 4 | trainingMode | TOE |
+-----+------------------------+---------+
For that user (uid 4) and any other user DSPAM is loading his preferences and
then merge them with the default (uid 0) but NOT overwriting user set
preferences. The result would look like this for user with uid 4:
+-----+------------------------+---------+
| uid | preference | value |
+-----+------------------------+---------+
| 4 | dailyQuarantineSummary | off |
| 4 | enableBNR | on |
| 4 | enableWhitelist | on |
| 0 | fallbackDomain | off |
| 0 | ignoreGroups | off |
| 0 | ignoreRBLLookups | off |
| 0 | makeCorpus | on |
| 4 | optIn | on |
| 4 | optOut | off |
| 0 | optOutClamAV | on |
| 0 | processorBias | on |
| 4 | showFactors | off |
| 4 | signatureLocation | headers |
| 4 | spamAction | tag |
| 4 | spamSubject | [SPAM] |
| 4 | statisticalSedation | 1 |
| 0 | storeFragments | off |
| 0 | tagNonspam | off |
| 0 | tagSpam | off |
| 0 | trainPristine | off |
| 4 | trainingMode | TOE |
| 0 | whitelistThreshold | 10 |
+-----+------------------------+---------+
And for user with uid 6 it will look like this:
+-----+------------------------+---------+
| uid | preference | value |
+-----+------------------------+---------+
| 0 | dailyQuarantineSummary | off |
| 0 | enableBNR | on |
| 0 | enableWhitelist | on |
| 0 | fallbackDomain | off |
| 0 | ignoreGroups | off |
| 0 | ignoreRBLLookups | off |
| 0 | makeCorpus | on |
| 6 | optIn | on |
| 6 | optOut | off |
| 0 | optOutClamAV | on |
| 0 | processorBias | on |
| 0 | showFactors | off |
| 0 | signatureLocation | headers |
| 0 | spamAction | tag |
| 0 | spamSubject | [SPAM] |
| 0 | statisticalSedation | 5 |
| 0 | storeFragments | off |
| 0 | tagNonspam | off |
| 0 | tagSpam | off |
| 0 | trainingMode | TOE |
| 0 | trainPristine | off |
| 0 | whitelistThreshold | 10 |
+-----+------------------------+---------+
That is pretty much what "dspam_admin aggregate preference <user>" does but it
does it regardless of the presence of the preference extension.
