I have just installed Version 6.0.1 (Build 4143) on our server. Everything works fine (till now) except receiving of mail. I logged in as admin, went to Mails tab, created a mail account (by clicking on settings). While I was creating mail account, it was able to connect to my mail server and I was able to select the INBOX and TRASH folder from the server folder list. After this when I come to the main mails window and click on Check Mail, I don't see any new mail, but surprisingly when I click on settings again, click on Test Settings and Done button, that time it says, please wait a moment and the new mails are appeared in the inbox folder. Then I send a mail to the configured account and click on Check Mail and again no new mail is displayed. Everytime I open the SETTINGS window and hit on Done button that time only it downloads the new mail.

Please Help
