Ticket reply uses recipient not sender

[rsc]

Infos:

• Used Zammad version: 6.2.0-1701867011.fdb4b0b7.jammy
• Used Zammad installation type: (source, package, docker-compose, …) package
• Operating system: Ubuntu Server 22.0.4
• Browser + version: Microsoft Edge 120.0.2210.133

Expected behavior:

• When I click reply on a ticket, it should use the mail of the sender as the recipient.

Actual behavior:

• When an agent created a ticket it looks like this:
  

  

• But if use reply, it’s using the recipient mail instead of the sender:
  

  

Steps to reproduce the behavior:

• Use the reply button on a ticket.

I know that there is a ticket already:
Ticket Reply, Replies to recipient not Sender - Technical assistance - Zammad - Community
But I couldn’t figure out how to solve this issue. Can someone please tell me in detail to fix it? Thank you.

OK, after some digging and testing I’ve found the solution:
I missed one email address that my IT team forgot to mention.

You have to enter all the email adresses (Aliases, etc.) related to that mailbox.
