PHP Imap not working when mailbox limit reached 50MB

Hi, I cant access the mailbox through PHP Imap when the mailbox quota limit reached 50MB. I changed the limit to unlimited in "Edit Users --> Mailbox --> Home Directory Quota - Unlimited", but still its not working Do I need to change the limit in somewhere else, please look into this. I m using Linux Ubuntu 18.04 LTS, PHP 7.2 Imap version



Howdy -- we're sorry that you're having a problem with IMAP.

It looks like you're using Virtualmin GPL there though, the area here is for folks using Virtualmin Pro.

It's no problem to get support!

But you'd want to use the Forums for support.

We monitor the Forums, along with lots of wonderful folks in the community. Thanks!
