You're completely right.. I did not think about that..

Hey Sergey.. What about to solve deal like that:

In the end of each installation of our software I'd like to send e-mail (with the costumer's data) addressed to our e-mail

Is there a way to catch the smtp server of user's machine ?

I meant.. of any e-mail account installed on his machine..

Thanks Sergey
