drop spam mail by user pref

[martin <ma...@excite.com>]

Dear all,
  spamd/spamc can had a user pref. file for user defined socring/white list etc,
and using milter (spamass-milter) to control drop the spam mail or not.
  my question is, can drop the spam mail based on user pref. file? e.g. some
user can decide to drop [marked] spam email, while other can still receive those
emails and filtering himself/herself.

  from man page, i found spamass-milter can use -u defaultuser to do some user
pref. action, but seem just passing to spamc.

  so, is it possiable to drop mail based on user pref?
  thx

 thx for fast reply.
 is procmail helpful in a system that only using sendmail for income/outgo email
and pop3 service (no imap) for user recv. email?

per-user prefs functions are best done at the delivery stage
(EG procmail).
milter like interfaces fit into the MTA chain and
thus operate on the message before delivery. At that stage a message
may have multiple recipients and thus you cannot identify one
paritcular user. (IE SA gets a single message that may have many
recipients so which user's prefs should it use?).

One way to achieve your desired goal would be to have SA tag the
messages at the MTA level and then craft your delivery agent
(EG procmail) to parse the SA headers and take action at
delivery time to drop a message or route it to a spam-bin folder
for each of the individual recipients.

We use a system that is structured that way. Thus I can SMTP reject
very high scoring spam and let the users decide what they want in
their INBOX or 'spam-bin' for what's left over.

  i understood this, so just want to ask any milter like interface (e.g
MailScanner, spamass-milter etc) can do such thing (not globally drop mail, but
based on user config)?

   thx a lot

SpamAssassin cannot be configured to drop mail at all.

Based on how SA integrates into the mail chain it can only modify the
contents of the message. It has no ability to delete or alter message
delivery.
