Hi Marc, i solved this using an automated report for users quarantine. In front of dovecot i have 2 mailscanner boxes that stores spam emails in quarantine and logs them to a database, periodically there is a script that sends an html report to users that recieved spam in the last interval (1h, 4h, 24hs depending on the user preferences) showing a list of time-from-subject of all new items in quarantine. There is also a link to release the email from quarantine and the users recieves it on his inbox. So our users can release emails without bothering anyone. (There is also an admin view where the admin can see all the trafic for the domain).

my 2cents.

regards,

eduardo.

Hi,

I'm looking for some advice to do a really advanced trick with Dovecot. I'm not sure if this can be done. I need to describe first.

I have a spam filtering company that does front end spam filtering. (Junk Email Filter) I want to add a system where I store a copy of spam on a server and make it available to the customer to review and maybe resent on false positives.

I know I could do something simple where I deliver all spam to a domain account and make it available to an administrator. Then if it's a false positive they would drag the message to a "resend" folder. I'll have something the checks the folder one a minute to pick up and resend.

However

What would be very cool is delivering the spam to individual accounts. So a user who logs in individually can see their own spam. But the admin for the domain would be able to see all users. Maybe the users would appear as folders?

Then a master account (me) would be able to log in and see all the domains as folders and the users as folders inside the domains?

One thing I can do is deliver the spam to 3 different places so it's visible on all levels.

I'm just wondering if anyone out there has any ideas about that. And I'll need an authentication system.

Maildir, layout=fs /var/vmail/domain/user/

Spams get delivered there. User has access there. Domain admin has mail_location=/var/vmail/domain, you have mail_location=/var/vmail

Check out the dovecot sieve plugin. I use the following default pre-filter for all users:

require ["regex", "fileinto", "imap4flags"];

# Catch mail tagged as Spam, except Spam retrained and delivered to the mailbox if allof (header :regex "X-DSPAM-Result" "^(Spam|Virus|Bl[ao]cklisted)$", not header :contains "X-DSPAM-Reclassified" "Innocent", not header :contains "Received-SPF" "pass .securityfocus.com") {

# Mark as read #setflag "\\Seen"; addflag "$junk"; # Move into the Junk folder fileinto "INBOX.Junk";

# Stop processing here stop; }

Together with the dovecot antispam plugin this makes the beginnings of a very intuitive system. I just click to remove the junk flag on any false positive, and it gets re-delivered to me.

The dovecot lda also supports a switch to deliver to a specific folder I believe. This would be an alternative if you get the spam delivered through a separate channel anyway.

The other part of your requirements could be met by using dovecot public folders, which I have never used myself. Maybe set up so admins can subscribe to the junk-folder of any user they want ? Refiling false positives might get messy for an admin though.
