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.
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.
