Submitting False Positive and False Negative Messages with MailShell Anti Spam You may encounter messages passing through the MailShell Anti Spam engine into your inbox that should of been rejected or find messages incorrectly identified as spam.

To ensure best performance you should make sure that you have the latest updates. You can verify this by looking at the timestamps of the definitions within the MailSite Console > Server > Filtering > MailShell Anti Spam Filter.

By default MailSite will check for updates every 5 minutes.

You may find some messages are delivered to the inbox which appear as spam. These false positives can be submitted to the FTP site below. The messages are then sent to your Anti Spam vendor for analysis.

There are 2 folders available:

• Is-spam - This is for messages that were delivered to the inbox but should have been detected as spam.
• Not-spam - Items that were caught by the engine incorrectly as spam

For correct analysis, we need the .msg file taken from the BOX directory on the server. This ensures the original messages are preserved. If a message has subsequently been forwarded or modified in any way it cannot be analysed correctly. The .msg files should be zipped and uploaded. You can zip multiple .msg files in one ZIP file.
