Restrictions by URL. Why is it necessary?

Let's suppose we've found that on some website there is a replacement of a necessary symbol (line) and EmEx 3 doesn't recognize it.

If we write a simple replacement rule, e.g. [at] to @, we will solve the problem. But why to do this on all scanned websites? This will only overload the processor after EmEx 3 work.

Just for this case we have implemented a restriction for this restriction rule. You write a restriction rule and limit its area of use by a certain URL. * and ? symbols are allowed as a mask.

For example to make the rule work only in EmEx 3 technical support you should write http://www.emex3.ru/support/* as a mask. So this rule won't work anywhere outside this section.
