My goal is prevent my work from disturbing - I want to read / check new emails after my action (F5). I use IMAP server because different devices. In server settings I have unchecked "check for new messages at startup" and "check for new messages ever xx minutes" but new emails still arrive. I tried to set longer period (100 minutes) but no change. I need active TB as source of information and also for sending answers, so switch to offline mode is bad choise. I have disabled notifications but if I see new mails, my mind wants to see what is new ;-) Please help me - any idea? Change some other setting? Some mailserver setting? Thanks a lot
