How do emails with + work in them, for example, " [e-mail] "

Question

How do these dynamic looking emails work? What is the role of this + in email addresses.

It seems that this is not a real mailbox that receives these letters.

My thinking is that they will go to " [e-mail] " when I read it somewhere. but what's the point then. Basically, I see this when you open a support ticket or stream, and you can directly respond to the email you receive, and the email response is added to the stream / ticket.

But I still don't understand how this works behind the scenes.

I am trying to implement something similar in my application where the user can reply to an email (I'm not sure what I should put for the reply address when sending the original mail) that we sent, and then I want to catch the answer or read it as- then in my script so that I can save it as a comment on the stream.

I use sendmail to send emails, and the address is currently set to " [e-mail] " .. somedomain.com is purchased from bluehost and the mx entries correspond to the settings provided by google applications.

and I have no idea what the next step is for me.
