Hello!
I need help!
I don 't know I have a problem or is it a roundcoube failure?
Once the mail user, for example baduser@domain.com filled his mailbox with 90% (1024 MB limit) and was informed by the mail server.
He cleaned his mailbox of extra letters, spam and cleared the trashbin.
I connect by ssh to the server console and check that the directory size is vmail1/domain.com/baduser = 160 MB, but roundcoube still shows 90% -91% -92% of the 1024 MB and continues to increase.
Checked on different computers, different browsers, cleaned the cache. Tried to switch roundcoube graphics interfaces. None of it helped.
Now I just increased the limit to 2048 MB and now it shows 46%, but I don 't know how to make the runcoube show the correct mailbox size. (160 MB of 2048 MB)
Maybe I 'm doing something wrong? And the runcoube shows not the size of the vmail1/domain.com/baduser directory?
Or can I start some kind of data conversion mechanism? Or do you want to restart any service on the server?
Restarting the entire server (host) failed...:)
I apologize for my bad English! This is the translator
I will be grateful for any help to me!
