Hi,

We're using a third party to scan our mails for spam and virus. Their standard way of handling mails that may or may not be spam is to put them in quarantine and send a report to the users and let them release the mail if it's legit.

I wish to change that so that they add ***SPAM*** to the subject and just send the mail to our Kerio Connect server which should then redirect the mail to the users junk mail folder. This gives us all mails with no delay which is quite important.

Is this possible? I have asked Kerio support but it doesn't seem like they really understand what I want to do, and I haven't been able to make it work myself by fidling with the SpamAssasin settings. It must be something that I can control from the console because it's not going to work if the users are required to create rules of their own.

Regards,
Rene Frej Nielsen

When we tested out spam filter, setting it to add **SPAM** to the subject was enough to have Kerio move messages to the Junk E-Mail folder.

Yes I have found out that it was actually doing that already. What I haven't found out yet is if it's nescessary to have Connects own spam filter enabled or if it will move the mails anyway?

FWIW, in my testing, incoming mail from the spam filter appliance comes from an IP on the local LAN segment. On the "Spam Filter" tab, I left "enable spam rating" checked, but had "enable rating of mail sent from trustworthy..." UNchecked. The way I interpret things, this will result in no black list checking, and no spam analysis. In effect, even though spam rating is enabled, it's never going to do anything.

I can't say for sure, but I believe that it is a rule that moves the messages to the Junk E-Mail folder, and not the anti-spam engine. But, I could be wrong.

The rule to move Spam to the Junk Mail folder is defined for every user and has nothing to do if Spam Rating is enabled or not.

You can find the file

filter.siv

in each user's store directory, in there you will see the rule:

#!1 __WebmailJunk__
if allof (spamtest, not address :all :is "From" "") {
  fileinto "Junk E-mail";
  stop;
}


I believe that the spamtest is looking into the header and checking for:

X-Spam-Flag: YES
