Quota gets calculated per user and per alias if you login with shadowaddress, so both emails gets their own quota. Problem is
when you login and clean messages as shadowaddress and relog as mail the quotas are different... so basically you just need to standardize the username to either one of them and have password_query and user_query return "user" field for that

pass_attrs      = userPassword=password
user_attrs  = homeDirectory=home,mailMessageStore=mail=maildir:/var/vmail/%$/Maildir/,mailQuota=quota_rule=*:bytes=%$

should be

pass_attrs      = mail=user,userPassword=password
user_attrs = mail=user,homeDirectory=home,mailMessageStore=mail=maildir:/var/vmail/%$/Maildir/,mailQuota=quota_rule=*:bytes=%$
