In this article we look at several aspects related to creating a macro strategy for dealing with spam emails in Ms Exchange.
Applying anti-spam techniques to MS Exchange might seem like something that does not have to be thought upon much. This is however one of the very common misconceptions held by Exchange users. As important it is to protect your mailbox server from spam and junk mail, equally important it is to strategize the protection method. You do not just have to simply apply the given anti-spam agents but adjust their aggressiveness and decide which ones to apply. By making an anti-spam strategy for Exchange, you can strike a balance between useless and useful mails. If you simply apply the anti-spam agents, they might be too aggressive that even the important mails get blocked, or too weak that even the unimportant mails reach you.
To avoid useful mails from getting blocked and useless mails from reaching you, it is advisable to create an anti spam strategy for MS Exchange. While creating a strategy, you should always keep the following points in mind:
- Do not quarantine or apply anti-spam stamps to the messages that have already been rejected by the Connection Filtering Agents, Sender Filter Agent or Recipient Filter Agent. The main reasons why you are advised to do this are:
- Once a message has been identified by either of the filtering agents, there is no need to get it further identified.
- You can save on the processing time, bandwidth, and disk resources if you configure an aggressive anti-spam strategy, to enable encountering the spam mails prematurely, in the transport pipeline.
- Make sure that the effectiveness of all anti-spam features is monitored at the level of their current configurations. By monitoring you can decide whether to increase or decrease the aggressiveness of the agents; it will also allow you to react on all trends.
- It is suggested to always begin by using the default settings; this will allow you to reduce the number of false positives. The monitoring of spam and false positives will allow you to change the aggressiveness of settings depending on the kind of spam attacks faced by your organization.
The Strategy Needs to be Well Thought Out
MS Exchange has lots of anti spam and filtering agents to provide its users with, but there is still a very high possibility that the users might still end up receiving spam mails. It might never be possible to entirely block the spam mails, because spammers today are also making use of advanced spamming methods. However a great deal of protection can be achieved if we strategize well before implementing the anti spam and the filtering agents.
