How to redirect mails to another mail

Hi, srry for my poor english.

I need to redirect ALL the mails starting with "pinpin" to a single mail.

Example:

pinpin.49822@mydomain.com
pinpin.5422@mydomain.com
pinpin.22@mydomain.com
pinpin.4522@mydomain.com

To a single one: "contact@mydomain.com"

I DO NOT WANT to create every email, manually, i just want to redirect every incoming email starting with "pinpin." to a single one.

Is there any way to do that ? mail forwarding? aliases?

Thanks a lot for your possible help!
