Individual user controlled spam quarantine on relay svr
Hi all, not sure if this should have been here in Servers or in Software, but since it is a server and server software I decided on the server forum.
I all ready have a Debian spam filter setup using Postgrey, Postfix, Amavis-new, spamassassin, and ClamAV this box is a relay spam filter server to our SBS Exchange Box. Currently all Virus laden email is disposed of, and all spam that is not thrown out gets sent to a spam filter account on the exchange server that I check periodically. This is inefficient and I'd rather not do this, additionally I'd like users to have control over their own white lists and so forth. I am willing to start from scratch on this as the spam filter is running in a VM environment I can plug a new one in and be running in minutes. The issue I am having is that I cannot find any information on how to do this. Plenty, including HOWTOs, on how to do this with local users on the spam box and also have it relay to another server, but not how to make quarantine folders for relay recipients that are accessable by the user and also how to notify the end user they have quarantines mail.
Can anyone here direct me, or point me in the right direction. I know this can be done because ISPs and spam filtering cloud providers do this. Thanks in advance.
P.S. I found a project, Spamvigilante, but it's prebuilt on freeBSD and I would prefer to run it on linux. My distro is Debian but I'm sure information for other distros would point me the right way.
