Setup: I have an email server running with virtual domains and virtual mailboxes that is currently hosting about 10GB of email across 15 domains and 8 mailboxes which will expand drastically once I get this to work. The server is an AWS EC2 instance with an AWS RDS instance for the database and using AWS EFS for storage. Everything works quite well except quotas!
Problem: I am having an issue with getting quotas to work. When using “doveadm”, I can list the mailboxes however the “Limit” column is just a hyphen “-“ like there is no limit even though every account is set to 10GB for their limit in the database. At the same time, the actual used storage and messages is not getting updated in the database either yet there are no errors from what I can see in the logging.

Where “username” is the first part of the email address and “email” is the full email address. I need to query using the full email address because of possible cross domain email addresses.

I have no idea what is wrong and I have been at this for over 12 hours trying to get the quotas to work. What I am expecting us when emails are delivered for the “quota” and “messages” columns in the “mailbox” table to be updated and when I run “doveadm quota get -A” to show me the current usages and limits for each mailbox. Once I have that working, I will move on to actually rejecting emails via Postfix + Dovecot LMTP when a users mailbox is full but right now, I am just trying to get this to work.
Any help is greatly appreciated. Also, I tried creating an account for the mailing list but never received the email.
Thank you!
