1. Why should I use this external spam filtering service? Doesn’t my server already have spam filtering?
If your domain is receiving a large volume of spam e-mail, it is likely causing an unnecessary burden on your server, and slowing down other operations on the server, such as handling web and database queries.For shared hosting accounts, large volumes of e-mail processing may consume excessive resources and require that you upgrade to a virtual or dedicated server. For dedicated servers, such e-mail processing may require you to purchase a higher end server to handle the load. By using this service, you reduce overall expenses and have a high-quality spam filtering solution. We have a custom designed and load balanced spam filtering cluster to handle the task of filtering your e-mail.
2. How does this service work?
Our load balanced spam filtering cluster acts as a “man in the middle” for your domain’s e-mail delivery. Mail is initially delivered to our servers, filtered, and the remaining “good” mail is forwarded on to your “real” mail server.
3. Can I configure spam filtering to filter and deliver e-mail for any user, so that it will be received by my catch-all mailbox?
No. The use of catch-all mailboxes results in a large volume of unnecessary CPU usage associated with filtering and delivery of spam e-mail. Therefore, individual recipient mailboxes must be defined.
4. What happens to messages that are flagged as spam by the spam filtering service?
Messages that are flagged as spam are saved for up to 7 days, and visible within your web interface. After a message has been saved for 7 days, it will be permanently deleted.
5. Will I still receive any spam after implementing your service?
Spammers are constantly changing their tactics to circumvent filters. For this reason, some spam may still be received after implementing our filtering service. We always keep our spam filtering systems up-to-date with the latest technologies to help avoid this. You may also adjust your filtering preferences to further reduce the amount of spam you receive.
6. Do mailbox users have access to a control panel for this filtering system?
Yes, we provide you with the ability to allow end users to access a control panel, where those users may view blocked messages, change filter sensitivity, and modify their individual whitelist and blacklist settings. However, you do not have to give mailbox users access to this control panel. You may maintain complete control of all settings at the domain level if you desire. The choice is yours.
