Why an off site service, why not an onsite product?
There are a number of advantages in providing centralised email services:
- It is easier and more cost effective to share hardware and support resource across multiple customers, making it far less expensive for the customer.
- The threat landscape changes very quickly, and by delivering the service on a smaller number of centrally managed devices we can react to new threats faster, thereby ensuring the highest level of email protection is maintained.
- The more email we process centrally the more accurate our systems become at spotting where spam is originating from, allowing us to block it more accurately.
- One of the problems associated with spam is that you receive so much of it that it eventually clogs up your Internet connection and email system, preventing legitimate email from getting through. By intercepting spam in the Internet it removes the adverse impact to your systems.
- If your Internet connection goes down or your email system is unavailable ImerjaMail will store your email so senders don’t get a failure message, then when your service is restored it will deliver the messages to you.
Do I need anything specific in place to use ImerjaMail?
You need to have your own email server, Exchange or Send Mail etc.
ImerjaMail will not work on webmail (such as pop, etc.) clients. If you use a webmail service delivered by an ISP or other organisation (such as Hotmail, Yahoo, etc.) it will almost certainly provide some level of anti-spam and anti-virus protection for you already.
What do I need to do to start using ImerjaMail?
Your email server needs to be configured to forward your out going email to the ImerjaMail service. Details of the required changes are presented in a Connection Guide. Guidance on how to make the changes can be obtained from your email system documentation, and from the examples available on the Implementation & Support FAQ.
You will also need to update you DNS records with the information provided (this is often done by your ISP on your behalf), so incoming emails are routed through the ImerjaMail service, again the details are presented in the Connection Guide.
If you have a firewall it is recommended that you configure it to only allow email from the ImerjaMail system to your email server and vice-versa. You can reference your firewall manufacture’s guides and the Connection Guide provided on this site.
