[Courier-imap] courier scale

[Andrew Woods]

Hi, we are building an application which uses courier imap. We need to run fine with 100,000 mailboxes overall. When we created 100,000 mailboxes and tried to view the mail in one of the boxes the following java mail exception was thrown.   2006-01-30 10:31:56,280 ERROR [com.anam.mmsportal.action.IMAPAction] Failed to Connect: could not connect to folder: INBOX on: localhost exception: javax.mail.MessagingException: * BYE Temporary problem, please try again later;   nested exception is:         com.sun.mail.iap.ConnectionException: * BYE Temporary problem, please try again later     I’m just wondering if there is a configuration file where a threshold for maximum amount of mailboxes is set?   Regards, Andrew
