Our company is evaluating the enterprise version of SpamFilter. So far so good, yet it would be nice to have each user review their spam folder using Outlook 2007 interface.

I found a helpful link:

The question is how to setup a web site for the service to work. Particularly, where do I take that ListSpam.asp required here:

Thanks in advance,
Victor.

Victor,

SpamFilter's installer has an optional component that will install a sample web interface under IIS that allows end users web access to their quarantine area. The "ListSpam.asp" file is part of the set of .asp files that is installed.

Thanks for your reply, Roberto.

Yesterday we had a deep thinking about if we really need that quarantine folder. The problem is that we are currently getting about 300K spam emails per day. Most of that is filtered by Exchange, although false positive rate is big enough. We plan to route all emails through this program and disable any other filters. Positive side is that we could have internal mail untouched. The negative is that all this junk could be quarantined and kill our hard drives, if enabled.

Because of this, a question arises. Is there a way to classify spam and move to quarantine only those letters, that could be potentially non-spam (result of Bayesian analysis or similar)? For instance, it's obvious that all incorrect MX are definitely spam, etc.

Neolisk,

For the vast majority of the filters that SpamFilter uses to detect spam, you can individually specify if emails blocked by that one filter are quarantined or not. This allows you to select which filter result in emails being quarantined and which in emails being completely deleted.

On average, each spam email that is quarantined requires about 25KB of space in the database. In your case, this amounts to about 7GB-8GB of spam-data that is accumulated each day.
If drive space is an issue, please note that you can configure SpamFilter to delete any quarantined emails that are older than x-number of days, which will keep the quarantine database from growing.

Thanks for answers you provided. They really helped a lot!

Now we have a problem with log files growing like hell. But we need this information! Is there an automated way to delete old logs? We would also like to be able to cut new ones into pieces to show on a website. Is that possible without custom scripting?

Hi Neolisk

300,000 SPAM is a lot for a single domain - are you an ISP or a single domain? Are you sure serious that your system is putting 300,000 SPAM into quarantine per day?

I've seen some small companies do several million connections per day, but never quarantine that many (guess I'm still too small).

You can have SpamFilter split the logs up into a maximum of 24 pieces per day (once per hour). You can find that setting in the spamfilter.ini file:

;Specifies how often the logfiles are rotated (Min=1, Max=24). The default is 24 (rotates at midnight). A value of 1 means every hour at the hour, value of 2 means at 2am, 4am, 6am etc...
RotateLogsEveryNNhours=24

I'm not sure about exact quantity, but yesterday the log file grew up to 124MB.

We own several domains and all of them are getting spammed. Were getting spammed. Situation improved since we installed this SpamFilter. And no, currently we are not saving any of those emails. Just because we are concerned about hard drive's health. Besides, nobody's going to read that much.

Thanks for configuration hint, yet I think even 5MB of logs per file (124/24) is too much to be downloaded and viewed through web. Gotta find some solution, probably and ASP.NET app to index into SQL db, but for now everyone seems already happy to have got rid of junk out of their mailboxes.

Before we decide to buy, need to investigate false positives. Anybody has enough stats on that?
