Filter Messages for the administrator

[symptome]

As administrator I get a lot of messages each day.
Is it possible that ...
when someone want's to write me a message, he sees some informations first:

- if you have got a question about technical cases, write to .....
- if ...

... and in the end the possibility to write to me.
So I just need a page to display first, but just if the message is for me.

Have you done something like this?

Thanx!
Marcel
