Plesk Bug: Unlimited Email but just a 100MB Mailbox

[Chris86]

Hi, i have created some service packages and give it some users. Then i have a problem, the mailbox was just 100MB large. Now i give every User the Package unlimited (where everything is unlimited), i see the mailbox from the user there stand: 96.8 MB used from unlimited. But if i make a thunderbird account it says 97% full, if i send a 6MB email, i get it back, mailbox is full...

How can i fix it, please help me.

Exactly the same problem here with Plesk 12.0.18 #68 on CentOS Linux 7.1.1503 (Core).
I started a subscription using a custom service plan with a mailbox size limit of 100 MB
After a few weeks I changed the service plan to Unlimited.
Unfortunately the mailbox size is still limited to 100 MB
Email sent to this box is bounced with
452 4.2.2 Mailbox full
