What happened?

I tried to send segment email and when I am using queue to send emails, messages do not have the following headers:

• List-Unsubscribe: List-Unsubscribe-Post;
• List-Unsubscribe-Post: List-Unsubscribe=One-Click
• List-Unsubscribe: <...>

when I switch from queue mode to "Send Immediately" and try to send new messages headers are there.

How can we reproduce this issue?

Step 1: Select Queue mode to send emails in settings
Step 2: Save the settings.
Step 3: Go and create segment email.
Step 4: Save it.
Step 5: Send the email.
Step 6: Run php bin/console mautic:emails:send
Step 7: Check the email headers. The above headers are missing.
