Separate contact form email from other mails send out by vB?

[dutchbb]

Does anyone know of a way to separate the vB contact form email address from the address used to send out automatic emails?

So that I can use "noreply@mysite.com" to send out automatic emails to members, and use "info@mysite.com" to receive contact emails.

Otherwise I have to deal with too many responses to automatic emails.

(Using a custom contact form is not an option).
