Replying to a message from: Rafael

Hello,

I am trying to use regular expressions in a content filter (in the body of the message).  I have a regexp that works, provided that Xeams uses PERL syntax.  The Users Manual says that regular expressions are "for advanced users", and I cannot find anything else on the topic.

Is there documentation on this topic, or examples of how to use regular expressions to detect, for instance phone numbers?

Thanks in advance,

Rafael
