Hi,
as is it now possible to send message later to avoid disturbing outside business hours, it would be nice to have the ability to set hours to check for new email, for each account.
When you have professionnal and personnal email account, you may want to receive personnal email without being calling back to your job by a new professional incoming email.
A cool other option would be a button (green/red) on the account in the folder tree to quickly switch on/off new incoming email check.
