What should be considered when configuring spam filters in Mimecast?

When configuring spam filters in Mimecast, it is crucial to continuously monitor and fine-tune settings based on the evolving threat landscape. This approach allows organizations to adapt to new spam techniques and tactics used by cybercriminals, as well as changes in business communication patterns. The nature of spam and email threats is ever-changing; therefore, a proactive stance is essential in maintaining effective spam filtering.

Regular review and optimization of spam filter settings help ensure that legitimate emails are not inadvertently blocked while maximizing the detection of unwanted or malicious emails. This ongoing process also aids in addressing false positives and negatives, improving overall email security posture.

While applying default settings might seem convenient, it does not account for the unique needs of an organization or the dynamic nature of email threats. Similarly, restricting emails solely from unknown senders is too simplistic, as threats can originate from previously trusted contacts whose accounts may have been compromised. Updating filters annually may not provide sufficient protection against rapidly evolving risks. Regular adjustments and monitoring are key to a robust email security strategy.
