On our server we receive malicious email from a specific sender. Is it possible with postfix to:
- Forward the emails received from this sender on a specific email (other domain name)
- Block these emails on our domain mailboxes

According to your question, you want to get rid of spam.
There are many ways to achieve this :
- read Fighting Spam - What can I do as an: Email Administrator, Domain Owner, or User?
- You can use canonical maps in postfix (http://www.postfix.org/canonical.5.html)
- You can use firewall rules to ban the malicious ip (iptables of pf setup can detailed depending on your os)
Update : If you really want to receive the mail and take appropriate action about it, like forwarding, archiving or executing a shell script, the best tools for you are procmail or maybe mailfilter :
- http://www.zer0.org/procmail/quickref.html provides documentation on how to "Forward to other address", "Feed to a shell command pipeline " or " Save to a folder ".
- mailfilter is my prefered tool for this type or problem, but it is necessary to have one configuration file per recipient
