Webmail Error

I am getting this error message when trying to delete an email via webmail…

ERROR : Could not complete request.
Query: COPY 20 "INBOX.Trash"
Reason Given: [ALERT] COPY failed - no write permission or out of disk space.

Anyone ever see this error before?

Has the E-mail account or user reached it’s quota? You can check this out in the Panel > Mail > Manage.

Or is your plan in general over it’s quota?

If not, then you need to contact support.
