Any of the items above can contain 3 magic strings, which are subsituted
as follows:
_DATE_ will be replaced with the current date in yyyymmdd format.
This will make archive-rolling and maintenance much easier,
as you can guarantee that yesterday\'s mail archive will not
be in active use today.
_HOUR_ will be replaced with the number of the current hour, with
a leading zero if necessary to make it 2 digits.
_TOUSER_ will be replaced with the left-hand side of the email
address of each of the recipients in turn.
_TODOMAIN_ will be replaced with the right-hand side of the email
address of each of the recipients in turn.
_FROMUSER_ will be replaced with the left-hand side of the email
address of the sender.
_FROMDOMAIN_ will be replaced with the right-hand side of the email
address of the sender.
If you give this option a ruleset, you can control exactly whose mail
is archived or forwarded. If you do this, beware of the legal implications
as this could be deemed to be illegal interception unless the police have
asked you to do this.
Note: This setting still works even if "Scan Messages" is no.

say that you want particular attachment names or types to be "disarmed"

The "rename" rules in filetype.rules.conf rename attachments that match
the rule according to this setting, where the string "__FILENAME__" will
be replaced with the attachment\'s original filename.
In filename.rules.conf, it is a little more complex. They can work just
like the filetype rules.conf version explained in the previous paragraph,
or else the "rename" instruction can also supply the replacement text.
For example, a rule starting
rename to .txt \\.reg$ .....
will match all attachment filenames ending in ".reg" and replace the
".reg" with ".txt".
The "rename" rules change the filename of the attachment as described
above, so that either
(a) the user cannot simply double-click on the attachment, but must save
it then rename it back to its original name; only then can they
double-click on the file.
OR
(b) the action taken when the user double-clicks on the file will be
changed. In the "reg"/"txt" example above, the file will be opened
for editing rather than immediately merged into the user\'s Windows
Registry, which could have had disastrous consequences.
This provides a simple safeguard so that users have to consciously
think about what they are doing, and do not accidentally take actions
they would probably regret. In some situations this is better than
just denying the file completely, as the user can still see the attachment
they were sent.

deliver - deliver the message as normal
delete - delete the message
store - store the message in the (spam) quarantine
store-nonmcp - store the message in the non-MCP quarantine
store-mcp - store the message in the MCP quarantine
store-nonspam - store the message in the non-spam quarantine
store-spam - store the message in the spam quarantine
store-<directory-path> - store the message in the <directory-path>
forward user@domain.com - forward a copy of the message to user@domain.com
See the note below about the keywords that
can be used.
striphtml - convert all in-line HTML content to plain text.
You need to specify "deliver" as well for the
message to reach the original recipient.
attachment - Convert the original message into an attachment
of the message. This means the user has to take
an extra step to open the spam, and stops "web
bugs" very effectively.
notify - Send the recipients a short notification that
spam addressed to them was not delivered. They
can then take action to request retrieval of
the original message if they think it was not
spam.
header "name: value" - Add the header
name: value
to the message. name must not contain any spaces.
The "value" may contain the magic keyword "_TO_"
anywhere in it. _TO_ will be replaced by a
comma-separated list of the original recipients
of the message. This is very useful if you just
forward the message to a new address and don\'t
use the "deliver" action, as otherwise the list
of the original recipients may be lost.
custom(parameter) - Call the CustomAction function in /usr/lib/Mail-
Scanner/MailScanner/CustomFunctions/CustomAction
.pm with the \'parameter\' passed in. This can be
used to implement any custom action you require.
"forward" keywords
==================
In an email address specified in the "forward" action, several keywords can
be used which will be substituted with various properties of the message:
_FROMUSER_ The left-hand side of the address of the sender.
_FROMDOMAIN_ The right-hand side of the address of the sender.
_TOUSER_ The left-hand side of each of the recipients in turn.
_TODOMAIN_ The right-hand side of each of the recipients in turn.
_DATE_ The date the message was received by MailScanner.
_HOUR_ The hour the message was received by MailScanner.
This means that you can forward messages to email addresses which show the
original recipients of the message, which could be very useful when
delivering into spam archive management systems.

handle spam when set to trust the "SpamAssassin" headers.

Once the size limit is reached, MailScanner reverses towards the start
of the message, until it hits a line that is blank. The message passed
to SpamAssassin is truncated there. This stops any part-images being
passed to SpamAssassin, and so avoids rules which trigger on this.
3) Put in a number followed by \'continue\' followed by another number.

added looking for a blank line. This tries to complete the image data

The "value" may contain the magic keyword "_TO_"
anywhere in it. _TO_ will be replaced by a
comma-separated list of the original recipients

forward the message to a new address and don\'t
use the "deliver" action, as otherwise the list

custom(parameter) - Call the CustomAction function in /usr/lib/Mail-
Scanner/MailScanner/CustomFunctions/CustomAction

used to implement any custom action you require.
"forward" keywords
==================
In an email address specified in the "forward" action, several keywords can
be used which will be substituted with various properties of the message:
_FROMUSER_ The left-hand side of the address of the sender.
_FROMDOMAIN_ The right-hand side of the address of the sender.
_TOUSER_ The left-hand side of each of the recipients in turn.
_TODOMAIN_ The right-hand side of each of the recipients in turn.
_DATE_ The date the message was received by MailScanner.
_HOUR_ The hour the message was received by MailScanner.
This means that you can forward messages to email addresses which show the
original recipients of the message, which could be very useful when
delivering into spam archive management systems.
The default value I have set here enables Thunderbird to automatically
handle spam when set to trust the "SpamAssassin" headers.

X-Mozilla-Status is bad as it allows spammers to make a message appear to
have already been read, which is believed to bypass some naive spam
filtering systems.
Receipt requests are bad as they give any attacker confirmation that an

store-mcp - store the message in the MCP quarantine
store-nonspam - store the message in the non-spam quarantine
store-spam - store the message in the spam quarantine
store-<directory-path> - store the message in the <directory-path>
bounce - send a rejection message back to the sender
forward user@domain.com - forward a copy of the message to user@domain.com
See the note below about the keywords that
can be used.
striphtml - convert all in-line HTML content to plain text.
You need to specify "deliver" as well for the
message to reach the original recipient.
attachment - Convert the original message into an attachment
of the message. This means the user has to take
an extra step to open the spam, and stops "web
bugs" very effectively.
notify - Send the recipients a short notification that
spam addressed to them was not delivered. They
can then take action to request retrieval of
the original message if they think it was not
spam.
header "name: value" - Add the header
name: value
to the message. name must not contain any spaces.
The "value" may contain the magic keyword "_TO_"
anywhere in it. _TO_ will be replaced by a
comma-separated list of the original recipients
of the message. This is very useful if you just
forward the message to a new address and don\'t
use the "deliver" action, as otherwise the list
of the original recipients may be lost.
custom(parameter) - Call the CustomAction function in /usr/lib/Mail-
Scanner/MailScanner/CustomFunctions/CustomAction
.pm with the \'parameter\' passed in. This can be
used to implement any custom action you require.
"forward" keywords
==================
In an email address specified in the "forward" action, several keywords can
be used which will be substituted with various properties of the message:
_FROMUSER_ The left-hand side of the address of the sender.
_FROMDOMAIN_ The right-hand side of the address of the sender.
_TOUSER_ The left-hand side of each of the recipients in turn.
_TODOMAIN_ The right-hand side of each of the recipients in turn.
_DATE_ The date the message was received by MailScanner.
_HOUR_ The hour the message was received by MailScanner.
This means that you can forward messages to email addresses which show the
original recipients of the message, which could be very useful when
delivering into spam archive management systems.
The default value I have set here enables Thunderbird to automatically
handle spam when set to trust the "SpamAssassin" headers.
This can also be the filename of a ruleset, in which case the filename
must end in ".rule" or ".rules".

actions taken on a message by adding or removing any action or actions,
depending on what SpamAssassin rules it matched.
It can be used to replace the functionality of MCP, but without the large
processing overhead that involves.
The setting consists of a comma-separated list of
SA_RULENAME=>action,action,...
pairs, where \'SA_RULENAME\' is the name of any SpamAssassin rule (or
meta-rule), and \'action\' is the name of any of the actions listed above
the \'Spam Actions\' configuration setting or the word "not-" preceding any
of the action names.
Preceding the action name with "not-" as in "not-deliver" or "not-forward
user@domain.com" will cause the action to be removed from the list of
actions that would normally be taken on this message.
All of the keywords available in the "forward" action also work here.
You can specify a comma-separated list of actions if you need more than 1
action per rule.
Example: Setting this to
SpamAssassin Rule Actions = FROM_BOSS_WIFE=>not-forward secretary@domain.com
would result in mail from the boss\'s wife not being forwarded to the boss\'s
secretary, which would be useful if the non-spam actions for the message
included forwarding to the boss\'s secretary.
You can also trigger actions on the spam score of the message. You can
compare the spam score with a number and cause this to trigger an action.
For example, instead of a SA_RULENAME you can specify
SpamScore>number or SpamScore>=number or SpamScore==number or
SpamScore<number or SpamScore<=number
where "number" is the threshold value you are comparing it against.
So you could have a rule/action pair that looks like
SpamScore>25=>delete
This would cause all messages with a total spam score of more than 25 to be
deleted. You can use this to implement multiple levels of spam actions in
addition to the normal spam actions and the high-scoring spam actions.
Combining this with a ruleset makes it even more powerful, as different
recipients and/or senders can have different sets of rules applied to them.
