I am able to log into my squirrelmail account but Im getting this error:
ERROR: Could not complete request.
Query: CREATE "INBOX.Sent"
Reason Given: Cannot create this folder.

ERROR: Could not complete request.
Query: SELECT "INBOX"
Reason Given: Unable to open this mailbox.

I am using Kubuntu-Postfix-CourierIMAP-Squirrelmail configuration for setting up a mail server.

Where do I create the directories for INBOX?? And where do I link this directory to squirrelmail? In squirrelmail config, there seems to be no such option.

Thanks in Advance.

unrelated to networking. moved to Linux - server.

run vi /etc/squirrelmail/config_local.php
then add these lines
$defaul_folder_prefix='INBOX.';
$trash_folder='Trash';
$send_folder='Sent';
$draft_folder='Draft';


when finished pres Esc
then type :wq! and press enter
