Hello, I am hoping that you can help me. I am running this command on my main email server, one way backup/sync to the backup server. sudo doveadm sync -1 -A remote:root@x.x.x.x

x.x.x.x is my remote server. I will add a new email on the main, run the command and it shows up on the backup.  - Great! Now I delete that email from the main, run the command and the email is removed from the backup.  That should not delete anything from the backup, correct?  I prefer Not to delete anything, only update/add. Do you see what I am doing wrong? Thank You!!!!
