Description

User stories:

1. 1. 1 Loop with existing user entry point

• Given a server with `rcpt1` and `rcpt2` users
• `sender` sends a mail to `rcpt1` which redirect to `rcpt2` which redirect to `rcpt1`
• Email is accepted by the SMTP / JMAP layer
• During RRT execution, the loop is detected and the email is stored in a Repository and a bounce is sent

1. 1. 2 Loop with existing user entry point

• Given a server without `rcpt1` but with `rcpt2` users
• `sender` sends a mail to `rcpt1` which redirect to `rcpt2` which redirect to `rcpt1`
• Email is accepted by the SMTP / JMAP layer
• During RRT execution, the loop is detected and the email is stored in a Repository and a bounce is sent

Today:

• 2. Needs to be accepted by SMTP layer (if there is too much mapping, the meaning is that we are interested by the entry).
• We need to ship proper configuration.

*Once donne add a looping test for Forward feature*! (This ticket is a blocker for adding such tests)
