You can move the directories within the dovecot vmail container (this keeps the email) .
create a new user in the mailcow interface (or use the api)
then get dovecot to recalculate the quota using doveadm
killmasta93 would i add this in the section of Custom parameters?
Yes
killmasta93 Yes. I rather not to allow users to do so. One man’s meat is another man’s poison. If you know what i mean
Manual training
Login to domainname.com/rspamd. You have to create a password under mailcow UI. System –> Configuration –> Access –> Rspamd UI
Under Scan/Train. Copy the header and body of the spam and paste into the dialog box. Hit Scan message and Upload SPAM.
If it is a HAM, then Upload HAM. After you hit 200 HAMs and SPAMs each, the system should be able to learn by itself. You also still can manually train the system
I guess your issue is that the desired client does not support modern TLS Standards
Try that maybe: 
Re-enable TLS 1.0 and TLS 1.1 - mailcow: dockerized documentation docs.mailcow.email
