I have configured a hmailserver with 2 mail ID. I have configured the same email ID in my Mozilla Thunderbird. When i click on inbox, i get the following message : "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server. If so, use the Advanced IMAP Server Settings dialog to reduce the number of cached connections.” Upon some searching in google i tried this solution : "Tools - Account Settings - [select your account] - Server Settings - [Server Settings section] - Advanced - Maximum number of server connections to cache - [Enter 3] If it is already set to 3, go lower - 2 or even 1." But didn't help. Can someone kindly look into this? Thanks
