SecurityGateway is a powerful email spam & malware filter & gateway that can be used to protect any type of mail server. It offers a layered approach to security, with protection features including data leak prevention, attachment filtering, heuristic and Bayesian analysis, zero-hour Outbreak Protection, and much more.
Whether you work in health care, finance, government, or any other field that requires the storage of data, there's always someone out there who would love to gain access to your confidential records. Don't let the bad guys steal your data. Protect it with server-side encryption. Our latest release of MDaemon supports OpenPGP, which allows MDaemon to perform encryption, decryption, and key management tasks. Learn how to enable OpenPGP support in MDaemon, and how to send encrypted mail in our latest video.
As we discussed in an earlier post, messages that users may receive in response to messages they never actually sent (due to their email addressed having been forged in a spam message's return-path) are known as backscatter. In that post, we discussed what backscatter is and explained how to enable Backscatter Protection in MDaemon.
Occasionally, our support staff will receive calls from end users who have forgotten their email password or are having issues logging into WorldClient. Users are then instructed to contact their mail server administrator for assistance. But what if users don't know who to contact for help, and don't know how to even find out who to contact? For some users, trying to track down the appropriate contact for help can lead to wasted time and lost productivity.
It is possible to create any number of schedules you wish. You can name each schedule and attach a schedule to a custom mail queue. You can also create as many custom mail queues as you want. Use the Content Filter to move messages into your custom queues based on any criteria you wish.
For example, you can create a schedule called 'Large Messages', create a queue to store those messages, and then create a Content Filter rule using the 'MOVE message to custom QUEUE' action to move messages over a certain size into that queue. If you'd like mailing list messages delivered at certain times then create a schedule called (for example) 'List Mail', create a queue, and then use a Content Filter rule to move messages with an X-MDMailing-List header into the new queue.
MDaemon's pruning feature allows you to remove old data from the server and free up disk space. You may be familiar with the Public Folder Pruning settings under the Server Settings menu, or the Account & Mail Pruning settings under the Domain Manager, but did you know you can fine-tune your pruning settings using a Command prompt? The command line interface allows you to be very specific about what you want to prune. For example, you can prune (remove) messages that are a specified number of days old (say, 15 days) for a sub-folder of the inbox of a specific account, have those messages moved to a designated public folder, or just have the pruning information logged without actually deleting any data so that you can run this feature in test mode.
