Thanks @tamimibrahim17,
To be honest. Very few changed.
1. logs work now, thanks.
2. I choose “Delete user” and this happened:
1. Subject : Undelivered Mail Returned to Sender
[email protected] Bounce reason : mailbox_not_available , Subscriber Add to list , Subscriber Current Status : Bounced , message deleted.
After checking the list of subscribers the user still exists but with status “bounced”
