Local verification of sending mail() via postfix?

Question

linux

The development of the PHP script is on the local machine (ubuntu 16.04), it came to checking the sending of mail () and the appearance of the letter. I do not want to upload to the combat server where the mail () function sends everything where necessary. I would like to test everything locally. Tell me, how can I receive letters locally, on ubuntu?
How to create a mailbox in postfix, such as [email protected], connect to it via Thunderbird and all test letters could be received on it?
