Hi Soren,
How many emails is a lot?
One solution would be to first create a Contact page and put an Html content feature on it. Then create child pages below it for each email address and add a Contact Form on the page configured to send to the specific email. You can use a captcha on the contact form to prevent spam bots.
Then go back to the Html content on the main contact page and link to each form without indicating the email, just use an alias like "Contact Sales", "Contact Support" or whatever and link to the child page that has the form.
Now after all that is done, optionally you can go to the page settings for each child page and un-check the "Include In Menu" if you don't want thos page in the menu but only want to link directly to them.
Another solution is to use just one contact form and the user chooses an email alias from a list. See this article:

I think using forms like this is the best way for people to contact you without publishing your email address in a way that spammers will scrape it. But, there are also techniques of obfuscating email addresses in html.
Hope it helps,
Joe
