Overview

As part of Mimecast's commitment to continuous improvement, we will be adding the ability to enable or disable URL re-writing for email subject lines via email policies.

What's changing

• A new option will be added to the URL configuration setting under the Detection Engines, this will allow customers to keep URL re-writing enabled with the added flexibility of being able to disable it for subject lines.

There are no actions required as a result of this change. This option will be on by default for existing customers but will be disabled for new customers as URL re-writing is also disabled.
 

Rewrite URLs in Subject Lines FAQs

Q:	How can I control if URLs found in Subject Lines are re-written?
A:	To provide greater flexibility, customers will be able to control if URLs found within subject lines are rewritten. This option will be found under the URL sections within the detection settings and this feauture is enabled by default.
Q:	What will happen if URLs are not rewritten consistently?
A:	This is caused by the moderate URL detection within Cloud Integration, as the aggressive setting causes a large number of false positives or customer issues.
